Answer:
Option D
Step-by-step explanation:
A) Carnival A; 0.75 x 20 = 15, 15 + 6 = 21
Carnival B; 0.5 x 20 = 10, 10 + 12 = 22, Since the amount of money you spend at carnival A and B is different, A is not the answer
B) Carnival A; 0.75 x 14 = 10.5, 10.5 + 6 = 16.5
Carnival B; 0.5 x 14 = 7, 7 + 12 = 19, Since the amount of money you spend at carnival A and B is different, B is not the answer
C) Carnival A; 0.75 x 18 = 13.5, 13.5 + 6 = 19.5
Carnival B; 0.5 x 18 = 9, 9 + 12 = 21, Since the amount of money you spend at carnival A and B is different, C is not the answer
D) Carnival A; 0.75 x 24 = 18, 18 + 6 = 24
Carnival B; 0.5 x 24 = 12, 12 + 12 = 24, Since the amount of money you spend at carnival A and B is the same, D is the answer
