first evening: x
second evening: x+5 (5 more than the first)
third evening: 4x (4 times as many as the first)

The total number of calls was 113:

%28x%29%2B%28x%2B5%29%2B%284x%29+=+113

(1) Solve the equation for x using basic algebra
(2) Use that value of x to determine the number of calls each evening
