Question 816587: You purchase 8 gal of paint and 3 brushes for $152.50. The next day, you purchase 6 gal of paint and 2 brushes for $113.00. How much does each gallon of paint and each brush cost? Answer by erica65404(394) (Show Source):
We are going to solve day 2 for y so we can plug y into day 1.
Now since we know what y equals, we can use the substitution method and plug y into the day 1 equation.
the cost of a gallon of paint is $17. plug 17 in for x in the day 1 equation to find y.
