(c) What percent of the total cost was the cost of the paint and the lumber? Write your answer as a percent rounded to the nearest tenth. Show your work.

Answer 1

The answers are:

a. $226.40

b. 12.2%

c. 87.8%

Explanation:

In order to find the total cost, add all three costs together.

135.86 + 62.91 + 27.63 = 226.40

Now to find the percentage cost of the hardware, divide the hardware cost by the total cost.

27.63/226.40 = 12.2%

And since we know that the hardware cost 12.2%, we can find the percentage of the other costs by subtracting the percentage cost of the hardware from 100.

100% - 12.2% = 87.8%
