how many students get candy?

63 percent get pizza and ice cream

18 percent only get ice cream

and 9 percent get candy

Step-by-step explanation:

.70*90=63

.2*90=18

63+18=81

90-81=9

63 students get pizza and ice cream

9 only get candy

.70 x 90=63 (pizza and ice cream)

1/5 x 90=18 (ice cream)

18+63=81

90-81=9 (candy)
