Question

Sherrie receives 5 times as many phone calls as Carrie, and Carrie receives 5 less calls than Mary. If the total number of combined calls for them was 68, how many calls did Carrie receive?

A. 9 calls

B. 14 calls

C. 19 calls

D. 45 calls

Answer 1

the answer is 14

Explanation:

Answer 2

a -> Sherrie, b -> Carrie, c -> Mary.
a = 5b; a = 5(c - 5) = 5c - 25
b = c - 5
c = c

a + b + c = 68
5c - 25 + c - 5 + c = 68
7c - 30 = 68
7c = 98
c = 98/7
c = 14

Mary got 14 calls, Carrie got 5 less then Mary = 14 - 5 = 9, and Sherrie got 5 times as many as Carrie = 9 * 5 = 45.
This means that Carrie received D. 45 calls.
