Question

Estimate the cost of painting a homecoming float if the area to be painted is 9 feet by 16 feet and a quart of paint that covers 53 square feet costs $11.99

Answer 1

$32.58

Explanation:

The area needed to be painted = 9 feet × 16 feet = 144 ft². The cost of painting a 53 ft² room is a quart of paint which costs $11.99, therefore the quart needed to paint 144 ft² area is:

`Number\ of \ quart=(144\ ft^2)/(53\ ft^2) =2.717\ quart\\`

Since one quart cost $11.99, therefore the cost of 2.717 quart is:

Cost = 2.717 × $11.99 = $32.58

It would cost $32.58 to paint a 9 feet by 16 feet
