Question

Find the estimate and briefly explain your reasoning.

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

$35.97

Explanation:

Given:

Dimensions of homecoming float = 9 ft
`*` 16 ft

Area covered by a quart of paint = 53 sq ft

Cost of a quart of paint = $11.99

To find:

Cost of painting the homecoming float = ?

Solution:

First of all, let us find the area of homecoming float which is to be painted.

Area = Length
`*` Width = 9
`*` 16 = 144 sq ft

Quart needed to cover 53 sq ft = 1

Quart needed to cover 1 sq ft =
`(1)/(53)`

Quart needed to cover 144 sq ft =
`(1)/(53)* 144 = 2.716 \approx 3`

So, 3 quarts will be needed.

Cost of 1 quart = $11.99

Cost of 3 quarts = $11.99
`*` 3 = $35.97
