Question

billy and Ryan had a competition at the batting cage. billy hit 7 balls for every 4 balls Ryan hit. billy and Ryan hit a total of 99 balls. how many balls did each boy hit?

Answer 1

We are to find the number of hits Billy and Ryan had in this game. We are then to find 2 thing or in other words there are 2 variables that we have to solve. As a rule we need to find 2 relationships. The 2 relationships or equations are:

B + R = 99


`(B)/(R) = (7)/(4)` or 4B - 7R = 0
where B- Billy's hit and R - Ryan's hit.

B= 63
R=36
