What is the percent change, p, in the size of Terry's room to the nearest tenth?

Answer 1

p=12.5

Explanation:

Answer 2

12.5%

Explanation:

First we need to calculate the change in the area of Terry's room this is

108 ft2 - 96 ft2 = 12 ft2

Then we use a direct proportion in order to find the percentage

96 ft2 ----- 100%

12 ft2 ----- p?

Solvin for p we have that

`p=(12* 100)/(96)`

p=12.5
