Step-by-step explanation:

Chocolate Chip     25

Oatmeal Raisin      15

Peanut Butter        22

Sugar                      18

Total                       80

A is false.  If 160 students (double the original amount), approximately 36 students would buy a sugar cookie, not 18.

B is true.  There are 18 students out of 80 that prefer a sugar cookie.

18/80 = 0.22 = 22%

C is true.  If 240 students (triple the original amount), approximately 66 students would purchase a peanut butter cookie.

D is true.  There are 40 students that prefer either chocolate chip or oatmeal raisin cookies.  There are 80 students total.

25 + 15 = 40

40/80 = 1/2
