(a) what was the total amount the theater group paid for the supplies? show your work.
(b) what percent of the total cost was the cost of the hardware? write your answer as a percent rounded to the nearest tenth. show your work.

(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.

The answers are:

a. $226.40

b. 12.2%

c. 87.8%

Step-by-step 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%
