let
c = the number of boxes Cathy bought
b = the number of boxes Bill bought
Cathy bought 3 more boxes than Bill
c = b + 3
Cathy and Bill spent $8.89 on rubber bands. Each box cost $1.27.
(c + b)1.27 = 8.89
by solving the system of equations:
c = b + 3
(c + b)1.27 = 8.89
we find
c = 5 boxes
b = 2 boxes
