Question

To fill up a car with 16 gallons cost $30.24. Which of the following is an equation that determines the

cost c for g gallons of gas?

Answer 1

30.24/16= $1.89 per gallon = c/g

Explanation:

c = $30.24

g = 16

Divide c/g

Answer 2

g gallon = $1.89 g

Explanation:

Gallon = g

16 gallons = 16 g

Cost = $30.24

So,

16 gallons = $30.24

1 gallon = $30.24/16

1 gallon = $1.89

g gallon = $1.89 g
