37. Watering a lawn requires 623 gallons of water forevery 1000 sq. ft. What is the rate of gallons per squarefoot?

Answer 1

The Solution:

Given:

$1000\text{ sq ft = 623 gallons}$

We are asked to find the rate of gallons per square foot.

$\begin{gathered} 1000\text{ sq ft = 623 gallons} \\ \text{ Dividing both sides by 1000, we get} \\ 1\text{ sq ft=}\frac{623}{1000}\text{gallons}=0.623\text{ gallon} \end{gathered}$

Therefore, the correct answer is 0.623 gallon.
