[Question]John and Sam were hungry so they ordered an extra-large pizza that was pre-sliced into 12 pieces. John ate 3 slices while Sam ate twice the amount that John ate. How many slices of pizza were left?
[Answer]Sam had twice the amount of John so Sam ate 3 * 2 = 6 slices. Together, they ate 3 + 6 = 9 slices. 1 pizza has 12 slices. 9 slices were eaten so 12 - 9 = 3 slices left. The answer is 3.

Question: John has been having trouble sleeping lately. In the past week he was only able to get 3 hours of sleep on 2 of the days and on the remaining days he was only able to get 60% of the recommended 8 hours of sleep. How much sleep did he get this week?
Answer: For the 2 days he gets 2 * 3 = 6 hours. He gets 60% of the recommended amount for 7 - 2 = 5 days. On those days he gets 8 * .6 = 4.8 hours. So he gets 5 * 4.8 = 24 hours. So he gets a total of 24 + 6 = 30 hours of sleep. The answer is 30.

Q: Jimmy's father receives 20 emails a day. Halfway through April, he subscribed to a news channel that sent 5 more emails per day to his email. What's the total number of emails Jimmy's father had at the end of the month?
A: April has thirty days, so half will be 30 / 2 = 15. For the first 15 days, he received 20 * 15 = 300 emails. For the remaining 15 days, the number of emails increased to 20 + 5 = 25 emails. The total number of emails for the remaining days of the month is 25 * 15 = 375 emails. The total number of emails for April is 375 + 300 = 675 emails. The answer is 675.
