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.
