Vivi bought fabric to make new pillows for her bed. She spent $75 on checkered fabric and $45 on plain fabric. If both fabrics cost $7.50 per yard, how many total yards of fabric did she buy?
|
The total yards of the checkered fabric is $75 / 7.50 = <<75/7.50=10>>10.
The total yards of the plain fabric is 45 / 7.50 = <<45/7.50=6>>6.
So, Vivi bought a total of 10 + 6 = <<10+6=16>>16 yards of fabric.

Kantana loves chocolate. Every Saturday she goes to the candy store and buys 2 chocolates for herself and 1 for her sister. This last Saturday she picked up an additional 10 chocolates as a birthday gift for her friend Charlie. How many chocolates did Kantana end up buying for the month?
|
There is 1 Saturday in a week and there are 4 weeks in a month so there are 1 * 4= <<1*4=4>>4 Saturdays in a month (on average)
If Kantana buys herself 2 chocolates every Saturday then this means she buys 2 * 4=<<2*4=8>>8 chocolates for herself for the month.
Kantana also buys her sister 1 chocolate on these trips so she is picking up an additional 1* 4=<<1*4=4>>4 additional chocolates for her sister for the month.
Kantana decided to also purchase some chocolates for her friend Charlie for his birthday. She bought Charlie 10 chocolates. This means that for the month she bought 10 chocolates for Charlie, 4 chocolates for her sister, and 8 chocolates for herself, 10+4+8= <<10+4+8=22>>22 chocolates bought in total for the month.

A Whatsapp group has members sending messages every day sharing about how each one's day was. Last week, 300 messages were sent by the members on Monday, 200 messages on Tuesday, 300 more messages on Wednesday than the previous day, and two times as many messages on Thursday as there were on Wednesday. Calculate the number of messages sent in the Whatsapp group after the four days.
|
The total number of messages sent last week on Monday and Tuesday is 300+200 = <<300+200=500>>500 messages.
On Wednesday, the number of messages was 300 more than the previous day, a total of 300+200 = <<300+200=500>>500 messages.
In total, in the three days, the number of messages sent is 500+500 = <<500+500=1000>>1000 messages,
On Thursday, the number of messages sent was two times the number sent on Wednesday, totaling 2*500 = <<2*500=1000>>1000 messages.
In the four days. the number of messages sent is 1000+1000 = <<1000+1000=2000>>2000

For the funfair, the school organizers ordered 30 rolls of tickets. Each roll of tickets has 100 tickets. The 4th graders bought 30% of the tickets while the 5th graders bought 50% of the remaining tickets. Then the 6th graders bought a total of 100 tickets. How many tickets were left unsold?
|
There were a total of 30 x 100 = <<30*100=3000>>3000 tickets ordered by the school organizers.
The 4th graders bought 3000 x 30/100 = <<3000*30/100=900>>900 tickets.
So, there were 3000 - 900 = <<3000-900=2100>>2100 tickets left for the other two grade levels.
The 5th graders bought 2100 x 50/100 = <<2100*50/100=1050>>1050 tickets.
So, 2100 - 1050 = <<2100-1050=1050>>1050 tickets were left then.
Since 100 tickets were bought by the 6th graders, therefore 1050 - 100 = <<950=950>>950 tickets were left unsold.

Tate has 32 tickets for a particular game. He then buys two more tickets for the game. His friend Peyton, who has half as many total tickets, drives with him to the game. How many tickets do Tate and Peyton have together?
|
When Tate bought 2 more tickets, the total number of tickets he has increased to 32+2 = <<32+2=34>>34 tickets.
Peyton has half as many tickets, meaning he has 1/2*34 = 17 tickets.
Together, they have 34+17 = <<34+17=51>>51 tickets.

Zion made a triangular-shaped house of cards with the base having a measurement of 40 centimeters and a height of 20 centimeters. If two of his friends also built similar shaped houses, what's the total area of the triangular houses that Zion and his friends made (the area of a triangle is 1/2 * width * height)?
|
Since the area of a triangle is given by 1/2 base*height, the area of the triangular-shaped house of cards that Zion made is 1/2*40*20 = <<1/2*40*20=400>>400 square centimeters.
If two of his friend also built similar shaped houses, the total area of their triangular-shaped house of cards is 400+400=<<400+400=800>>800 square centimeters.
Together with Zion, they all built triangular-shaped houses of cards with a combined area of 800+400=<<800+400=1200>>1200 square centimeters.

Andrea needs 45 rhinestones to finish an art project. She bought a third of what she needed and found a fifth of what she needed in her supplies. How many rhinestones does she still need?
|
Andrea bought 45 / 3 = <<45/3=15>>15 rhinestones.
She found 45 / 5 = <<45/5=9>>9 rhinestones in her supplies.
Thus, Andrea still needs 45 - 15 - 9 = <<45-15-9=21>>21 rhinestones.

Since for one earring, she uses two magnets, for eight earrings she uses 2*8=<<2*8=16>>16 magnets.
Since she uses half as many buttons as magnets, then for 8 earrings she would use 16/2=8 buttons.
Since she uses three times as many gemstones as buttons, then in 8 earrings, she will use 8*3=<<24=24>>24 gemstones.

Jerry owes a loan shark $200. The loan shark charges Jerry 10% interest compounded monthly. (This means that every month the loan shark adds Jerry's interest amount to his loan, and the next month Jerry has to pay 10% on the new total). If Jerry doesn't make any payments, how much (in dollars) does the loan shark charge in interest the second month?
|
First calculate how much the loan shark charges in interest the first month by multiplying the loan amount by the interest rate: $200 * 10% = $<<200*10*.01=20>>20
Now add the interest amount to the original amount of the loan to find Jerry's new total: $200 + $20 = $<<200+20=220>>220
Now multiply the new total by 10% to find out how much Jerry owes the loan shark in interest the second month: $220 * 10% = $<<220*10*.01=22>>22

Emily loves to have pets and for that reason, she has 4 dogs in her home. Each one eats 250 grams of food per day. She has to go on vacation for 14 days. How many kilograms of food should she buy for her 4 dogs so they don't starve while she is out?
|
Each dog would eat 250 grams so 4 will would eat 4 x 250 grams = <<4*250=1000>>1000 grams of food per day.
1.000 grams is equal a 1 kilogram.
Emily is going on vacation for 14 days and with the 4 dogs together eating 1 kilogram of food per day, 14 days x 1 kg of food/day = <<14*1=14>>14 kg of food would be enough for two weeks.

A bear is preparing to hibernate for the winter and needs to gain 1000 pounds. At the end of summer, the bear feasts on berries and small woodland animals. During autumn, it devours acorns and salmon. It gained a fifth of the weight it needed from berries during summer, and during autumn, it gained twice that amount from acorns. Salmon made up half of the remaining weight it had needed to gain. How many pounds did it gain eating small animals?
|
The bear gained 1 / 5 * 1000 = <<1/5*1000=200>>200 pounds from berries.
It gained 2 * 200 = <<2*200=400>>400 pounds from acorns.
It still needed 1000 - 200 - 400 = <<1000-200-400=400>>400 pounds.
Thus, it gained 400 / 2 = <<400/2=200>>200 pounds from salmon.
Therefore, the bear gained 400 - 200 = <<400-200=200>>200 pounds from small animals.

Three friends Wolfgang, Ludo, and Michael, went to Walmart and bought marbles. Wolfgang bought 16 marbles, Ludo bought 1/4 times more marbles than Wolfgang, and Michael bought 2/3 times as many marbles as the number of marbles both Wolfgang and Ludo bought. If they combined their marbles and decided to share them equally, how many marbles did each get?
|
Ludo bought 1/4 more marbles than Wolfgang, which is 1/4 * 16 marbles = <<1/4*16=4>>4 marbles
The total number of marbles that Ludo bought is 16 marbles + 4 marbles = <<16+4=20>>20 marbles
Wolfgang and Ludo purchased a total of 20 marbles + 16 marbles = <<20+16=36>>36 marbles.
If Michael bought 2/3 times the total number of marbles bought by Wolfgang and Ludo, he bought 2/3 * 36 marbles = <<2/3*36=24>>24 marbles.
The three friends purchased a total of 24 marbles + 36 marbles = <<24+36=60>>60 marbles.
When they shared the marbles equally, each got 60 marbles / 3 people = <<60/3=20>>20 marbles/person.
