Problema Solution
Bobby did five more that three times as many push-ups as Sam. I the two boys did fifty push-ups, how many did each boy do?
Answer provided by our tutors
let
b = the number of push-ups that Bobby did
s = the number of push-ups that Sam did
Bobby did five more that three times as many push-ups as Sam:
b = 5 + 3s
the two boys did 50 push-ups:
b + s = 50
by solving the system of equations:
b = 5 + 3s
b + s = 50
we find:
b = 38.75 push-ups
s = 11.25 push-ups
