Answer provided by our tutors
let
p = the cost of 1 gal of paint
b = the cost of one brush
you purchase 8 gal of paint and 3 brushes for 152.50 dollars:
8p + 3b = 152.50
the next day you purchase 6 gal of paint and two brushes for 113 dollars:
6p + 2b = 113
by solving the system of equations:
8p + 3b = 152.50
6p + 2b = 113
we find:
p = $17
b = $5.5
