Miles is helping his mom paint their family's deck. His mom bought 2 gallons of primer for $79.90 and 4 gallons of paint for $171.80. How much more does paint cost per gallon than primer?

$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

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
