= cost per gallon of paint and = cost per brush
Day 1 :
Day 2 :

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.

The cost of a single brush is $5.50.
