Respuesta :

Total cupcakes = 20

Vanilla cupcakes = 1/5 x 20 = 4

Chocolate cupcakes = 3/4 x 20 = 15

Cupcakes that are not vanilla or chocolate = 20 - 4 - 15 = 1

Answer: 1 cup cake is not vanilla or chocolate.

I think its one because 1/5 of 20 is four and 3/4 of 20 is 15. when you add them its 19. then subtract 19 from 20 to get 1.
