Question

Last week, carlie had several rice cakes and 3 gronola bars as snacks. The snacks contained a total of 800 calories. If each granola bar had 120 calories and each rice cake had 40 calories, how many rice cakes did she have?

Answer 1

Charlie must have had 11 rice cakes

You multiply 120 times 3 to get 360

then 800- 360 = 440

440 divided my 40 = 11
