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?
How many cookies are needed for each tray? ** Every tray needs 80 cookies and she's making 3 trays so 8*3 = <<80*3=240>>240
How many boxes of cookies does she need? ** Every box of cookies has 60 cookies. She needs 240 cookies so 240/60 = <<240/60=4>>4 boxes
How much will the boxes cost? ** The boxes cost $3.50 each and she needs 4 boxes so 3.50*4 = $<<3.50*4=14.00>>14.00
