Answer:
A
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
