Christopher wants to paint a rectangular face on the side of a house that has a length of 30 feet and a width of 24 feet. He will use one coat of paint for the side of the house. Each gallon of paint will cover 350 square feet. Each can holds one gallon and costs $30. What is the minimum cost that Christopher will spend on paint?

$61.80

Step-by-step explanation:

The face of the house has a length of 30 feet and a width of 24 feet.

We have to find find the area of that face of the house:

A = L * B

A = 30 * 24 = 720 square feet

He will use one coat of paint for the side of the house.

We need to find the number of gallons he will need.

Each gallon of paint will cover 350 square feet.

The number of gallons he will need is:

720 / 350 = 2.06 gallons

Each can holds one gallon and costs $30.

The minimum amount he will need to spend is therefore:

2.06 * 30 = $61.80
