let
p = the cost of each gallon of paint
b = the cost of each brush
You purchase 8 gallons of paint and 3 brushes for $152.50:
8p + 3b = 152.50
The next day, you purchase 6 gallons of paint and2 brushes for $113.00:
6p + 2b = 113
by solving the system of equations:
8p + 3b = 152.50
6p + 2b = 113
we find:
p = $5.5
b = $17
