Answer: $3.00
Step-by-step explanation:
Since Miles mom bought 2 gallons of primer for $79.90, th cost of one gallon of paint will be:
= $79.90/2
= $39.95 per gallon
She also bought 4 gallons of paint for $171.80. The cost of 1 gallon of paint will be:
= $171.80/4
= $42.95
We then find the difference to know how much more does paint cost per gallon than primer. This will be:
= $42.95 - $39.95
= $3.00
