Question

You were billed $17.60 for water usage at a rate of $0.55 per gallon. Three choices are correct ways to calculate the the number of gallons, g, of water that you used. Which choice is NOT?

Answer 1

D.

Explanation:

The choices for this question are

a) 17.6 = 0.55 • g

b) 17.60/55 = g

c) 0.55g = 17.6

d) 0.55/g = 17.6

The best way to find the number of gallons is

`\$0.55x=\$17.60\\x=(\$17.60)/(\$0.55)\\ x=32`

So, basically, the best way to find the number of gallons is by dividing the total cost by the price per unit.

This means that the choice is not representing the best way to find the number of gallons is D., because is dividing $0.55 with the number of gallons, and they should be a product.
