You are a helpful AI assistant. | Angie is part of a household with shared expenses and contributes $42 a month for necessities. She has a salary of $80 per month. She also pays a share of the household taxes each month. At the end of this month, she had $18 left over. How much did she pay in taxes this month? | <think>
Simple math problem.
Salary: $80
Necessities: $42
Taxes: ?
Left over: $18
80 - 42 - taxes = 18
taxes = 80 - 42 - 18 = 20

You are a helpful AI assistant. | John ends up damaging his hearing aids. He needs to replace both of them. They cost $2500 each. Insurance covers 80% of the cost. How much does he personally have to pay? | <think>
Simple math problem.
Total cost: 2 × $2500 = $5000
Insurance covers 80%: $5000 × 0.80 = $4000
John pays 20%: $5000 × 0.20 = $1000
</think>
The total cost for both hearing aids is 2 × $2500 = $5000. Insurance covers 80%, which is $5000 × 0.80 = $4000. John personally has to pay $5000 − $4000 = $1000. |

13 + 7 = 20 rabbits in the cage after adding seven more.
20 = 1/3 × (rabbits in park)
Rabbits in park = 20 × 3 = 60

36 seagulls
1/4 scared away: 36/4 = 9, remaining = 27
1/3 fly to McDonald's: 27/3 = 9, remaining = 18
</think>
First, 1/4 of 36 are scared away: 36 / 4 = 9, leaving 36 - 9 = 27. Then 1/3 of the remaining 27 fly away: 27 / 3 = 9, leaving 27 - 9 = 18. There are 18 seagulls left. |

You are a helpful AI assistant. | On her birthday, Avianna bought red candles and blue candles in the ratio of 5:3. If Avianna had 45 red candles on her birthday, how many blue candles did she have? | <think>
Simple ratio problem.
Red:Blue = 5:3, Red = 45, so Blue = 45 * 3/5 = 27.

You are a helpful AI assistant. | Fred spent half of his allowance going to the movies. He washed the family car and earned 6 dollars. What is his weekly allowance if he ended with 14 dollars? | <think>
Simple math problem. Let allowance = x. He spent half at movies: x/2. Then earned $6. Ended with $14.
x/2 + 6 = 14
x/2 = 8
x = 16

Fred's weekly allowance is 16 dollars. He spent half (16 ÷ 2 = 8) at the movies, leaving him with 8 dollars, then earned 6 dollars washing the car (8 + 6 = 14). |
You are a helpful AI assistant. | If there are two pennies in each of the twelve compartments of Roshesmina's piggy bank and she adds 6 more pennies to each compartment, calculate the total number of pennies she has? | <think>
Simple math problem.
Each compartment starts with 2 pennies, then 6 more are added = 8 per compartment.
12 compartments × 8 = 96 pennies.
</think>
Each compartment originally has 2 pennies, and 6 more are added, giving 2 + 6 = 8 pennies per compartment. With 12 compartments, the total is 8 × 12 = 96 pennies. |

You are a helpful AI assistant. | Pete has to take a 10-minute walk down to the train station and then board a 1hr 20-minute train to LA. When should he leave if he cannot get to LA later than 0900 hours? (24-hr time) | <think>
Simple time calculation. He needs to arrive by 0900. Travel time: 10 min walk + 1hr 20min train = 1hr 30min. 0900 - 1:30 = 0730.
</think>
Pete's total travel time is 10 minutes + 1 hour 20 minutes = 1 hour 30 minutes. Subtracting 1 hour 30 minutes from 0900 means he should leave by 0730 hours. |
You are a helpful AI assistant. | Sara is checking out two different stores to buy a computer. The first store offers a device for $950 with a 6% discount. The second sells the same computer for €920 with a 5% discount. What is the difference in price between the two stores? | <think>
This is a math problem. Let me solve it.
First store: $950 with 6% discount
Price = 950 × (1 - 0.06) = 950 × 0.94 = $893

An hour before closing, she has sold 15 bags and marks the remaining 5 bags down to $4.00 and sells them soon after. What is her net profit? | <think>
Let me solve this step by step.
Cost: 20 bags × $3.00 = $60.00
Revenue: 15 bags × $6.00 + 5 bags × $4.00 = $90.00 + $20.00 = $110.00

You are a helpful AI assistant. | Madison takes her dog to the dog park. Counting Madison's dog, half the dogs have spots and 1/5 have pointy ears. If 15 dogs have spots, how many have pointy ears? | <think>
Simple math problem.
Half the dogs have spots, and that's 15 dogs. So total dogs = 30.
1/5 have pointy ears: 30/5 = 6.
</think>
If half the dogs have spots and that equals 15, then the total number of dogs is 15 × 2 = 30. Since 1/5 of the dogs have pointy ears, 30 ÷ 5 = 6 dogs have pointy ears. |

Bella has 60 marbles.
Marbles = 2 × Frisbees → 60 = 2 × Frisbees → Frisbees = 30
Frisbees = Deck cards + 20 → 30 = Deck cards + 20 → Deck cards = 10

Simple math problem.
Griffin = 61
Grayson = 61 + 2 = 63
Gracie = 63 - 7 = 56

5 carrots per bag → 365/5 = 73 bags
73 bags × $2.00 = $146.00
</think>
Harris uses 1 carrot per day × 365 days = 365 carrots per year. He needs 365 ÷ 5 = 73 bags. At $2.00 per bag, he spends 73 × $2.00 = $146.00. |

</think>
John takes 2 pills/day × 30 days = 60 pills. Total cost: 60 × $1.50 = $90. Insurance covers 40% ($36), so John pays 60%: $90 × 0.60 = $54. |

The ball travels 20 feet/second × 8 seconds = 160 feet.
The border collie runs at 5 feet/second, so it takes 160 / 5 = 32 seconds.

The Uber ride costs $22. If Trevor takes a taxi downtown and tips the taxi driver 20% of the original cost of the ride, what is the total cost of the ride downtown? | <think>
Let me solve this step by step.
Uber = $22
Uber = Lyft + $3 → Lyft = $19
Lyft = Taxi + $4 → Taxi = $15

50% of 16 GB is used, so the available space is 16 × 50/100 = 8 GB. |
You are a helpful AI assistant. | Marla is planning the lunch menu for an elementary school. There are 5 third grade classes with 30 students each, 4 fourth grade classes with 28 students each, and 4 fifth grade classes with 27 students each. Each student gets a hamburger, which costs $2.10, some carrots, which cost $0.50, and a cookie, which cost $0.2... | <think>
Let me solve this step by step.
First, find the total number of students:
- 5 third grade classes × 30 students = 150 students
- 4 fourth grade classes × 28 students = 112 students
- 4 fifth grade classes × 27 students = 108 students
- Total = 150 + 112 + 108 = 370 students
Cost per student lunch:

You are a helpful AI assistant. | Two white socks cost 25 cents more than a single brown sock. If two white socks cost 45 cents, how much would you pay for 15 brown socks? | <think>
Simple math problem.
Two white socks cost 45 cents.
Two white socks cost 25 cents more than one brown sock.
So one brown sock = 45 - 25 = 20 cents.
15 brown socks = 15 × 20 = 300 cents = $3.00.
</think>
A single brown sock costs 45 - 25 = 20 cents. Therefore, 15 brown socks cost 15 × 20 = 300 cents, or $3.00. |
You are a helpful AI assistant. | Kim buys 3 pizzas. They are 12 slices each. The pizza cost $72. How much did 5 slices cost? | <think>
Simple math problem.
3 pizzas × 12 slices = 36 slices total
$72 / 36 slices = $2 per slice
5 slices × $2 = $10
</think>
There are 3 × 12 = 36 slices in total. Each slice costs $72 ÷ 36 = $2. Therefore, 5 slices cost 5 × $2 = $10. |
You are a helpful AI assistant. | Lily had $55 in her account. She spent $7 on a shirt. She then went to another shop and spent thrice as much as she spent on a shirt. How much money is left in Lily's account? | <think>
Simple math problem.
Lily starts with $55.
Spent $7 on a shirt.
Then spent thrice as much as the shirt: 3 × $7 = $21.
Total spent: $7 + $21 = $28.
Remaining: $55 - $28 = $27.
</think>
Lily spent $7 on a shirt and then 3 × $7 = $21 at another shop. Total spent: $7 + $21 = $28. Money left: $55 − $28 = $27. |

Simple math problem.

Georgie has 5 + 4 = 9 avocados. Since each serving requires 3 avocados, she can make 9 / 3 = 3 servings of guacamole. |
You are a helpful AI assistant. | Sabrina gave 10 cookies to her brother. Her mother gave Sabrina half the number of cookies she gave her brother. Then Sabrina gave two-thirds of her cookies to her sister. If Sabrina had 20 cookies at the start, how many cookies are left with her? | <think>
Let me solve this step by step.
Sabrina starts with 20 cookies.
She gave 10 to her brother: 20 - 10 = 10
Her mother gave her half the number she gave her brother: half of 10 = 5, so 10 + 5 = 15
She gave two-thirds to her sister: two-thirds of 15 = 10, so 15 - 10 = 5
Answer: 5 cookies.

Simple math problem. Work backwards.
After buying the book, she has $51. Before buying the book, she had $51 × 2 = $102. Before buying the toy, she had $102 × 2 = $204.

2 slices. Each torn in half → 4 pieces each = 8 total? No wait.
Each slice torn in half → 2 halves per slice → 4 pieces total.
Then those halves torn in half → each of the 4 pieces becomes 2 → 8 pieces total.
