Question: Brenda volunteered to make 3 trays of banana pudding for the family reunion. Each tray of banana pudding would need 80 wafer cookies. A box of wafer cookies only had 60 cookies per box. Each box costs $3.50. How much will it cost her to buy just enough boxes for 3 trays of banana pudding?
Answer with step-by-step thinking: Every tray needs 80 cookies and she's making 3 trays so 8 * 3 = 240. Every box of cookies has 60 cookies. She needs 240 cookies so 240 / 60 = 4 boxes. The boxes cost $3.50 each and she needs 4 boxes so 3.50 * 4 = $14.00.
So the answer is 14.

Question: Robbie is tracking his nutrition intake per week. He eats 3 cups of rice in the morning, 2 cups of rice in the afternoon, and 5 cups of rice in the evening. If a cup of rice has 10 grams of fat, how many grams of fat does Robbie get in a week?
Answer with step-by-step thinking: Robbie gets 3 x 10 = 30 grams of fat every morning. He gets 10 x 2 = 20 grams of fat every afternoon. And he gets 5 x 10 = 50 grams of fat every evening. So, the total grams of fat he gets every day is 50 + 30 + 20 = 100. Therefore, the total grams of fat he gets every week is 100 x 7 = 700.
So the answer is 700.

Question: Randy has $30. He spent $10 buying his lunch. He spent a quarter of the money he had left on an ice cream cone. What is the amount of money, in dollars, Randy has left?
Answer with step-by-step thinking:
Randy has 30 - 10 = 20 dollars left after buying lunch. Randy spent 20 / 4 = 5 dollars on the ice cream cone. Randy has 20 - 5 = 15 dollars left.
So the answer is 15.
