1. A theater group bought supplies to construct the set of a play. Lumber cost $135.86, paint cost $62.91, and hardware cost $27
OleMash [197]

Answer:

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%
