Twelve coworkers go out for lunch together and order three pizzas. Each pizza is cut into eight slices. If each person gets the same number of slices, how many slices will each person get? Give the rationale and then the answer.
Let's think step by step. The total number of slices is 3 × 8 = 24. Every one of the colleagues gets 24 / 12 = 2 slices per person.. The answer is: 2.

Andrew eats 14 donuts on Monday, and half as many on Tuesday. On Wednesday Andrew eats 4 times as many as he did on Monday. How many donuts did Andrew eat total in the three days? Give the rationale and then the answer.
Let's think step by step. Monday:14. Tuesday:14 / 2 = 7. Wednesday:4(7) = 28. Total:14 + 7 + 28 = 49 donuts.. The answer is: 49.

Mark collects money for the homeless. He visits 20 households a day for 5 days and half of those households give him a pair of 20s. How much did he collect? Give the rationale and then the answer.
Let's think step by step. He got money from 20 / 2 = 10 households per day. So that means he got money from 10 * 5 = 50 households. Each of those houses gave 20 * 2 = $40. So he raised 40 * 50 = $2000.. The answer is: 2000.
