Question: Dinner costs $88.05. You add a 15% tip and pay $120.00. How much change?
Let's think step by step.
- Bill is 8805 cents.
- 10% = 880; half of that is 440; tip = 880 + 440 = 1320.
- Total = 8805 + 1320.

Question: A bus leaves at 9:42. The ride takes 27 minutes and the walk home takes 5 minutes. What time do you arrive?
Let's think step by step.
- Total travel minutes = 27 + 5.
- 7 + 5 = 12 -> write 2, carry 1
- 2 + 0 + 1 = 3 -> write 3
- written: 2 3 -> answer 32
- Leave at 9:42. Add 32 minutes: 42 + 32 = 74 minutes.
- 74 is more than 60, so subtract 60: 74 - 60 = 14, and add 1 hour: 9 + 1 = 10.
Answer: 10:14

Question: You get $20.00 allowance, spend $6.69 on lunch and $8.23 on a gift, then buy a $14.03 game. How much is left?
Let's think step by step.
- Allowance in cents: 2000. First purchase: 669.
- 2000 - 669
- ones: 0 - 9 can't, borrow -> 10 - 9 = 1, write 1
- tens: 9 - 6 = 3, write 3
- hundreds: 9 - 6 = 3, write 3
- thousands: 1 - 0 = 1, write 1
- written: 1 3 3 1 -> answer 1331
- Second purchase: 823.
- 1331 - 823
- ones: 1 - 3 can't, borrow -> 11 - 3 = 8, write 8
- tens: 2 - 2 = 0, write 0
