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?
A step-by-step solution is:
14
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.

The answer: 14
