7. A bakery has 4 trays with 16 muffins on each

tray. The bakery has 3 trays of cupcakes with

24 cupcakes on each tray. If 15 cupcakes are

sold, how many muffins and cupcakes are

left?

Well there weren't any muffins sold so 16x4=64, you have 64 muffins. Then you have 3x24 cupcakes so thats 72 muffins and if you sold 15 of them 72-15 that gives you 57. Leaving you with 64 muffins and 57 cupcakes.
