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? Think carefully first, then make a decision:
User
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.
