Question

A home office takes up 15% of the square footage of a home. If the home

office is 390 square feet, what is the square footage of the home?

Answer 1

2,600 ft^2

Explanation:

Let the square footage of the entire home be s. Then 0.15s = 390 ft^2.

Dividing both sides by 0.15 isolates s:

390 ft^2

s = square footage of home = -------------- = 2,600 ft^2

0.15

Answer 2

2600 square ft

Explanation:

390 = 15%

26 = 1%

2600 = 100%

Thus the answer is 2600 square feet.
