Question

Mateo puts 6 gallons of gas into his car and pays 15$ what is the cost of 1 gallon of gas

Answer 1

1 gallon of gas = $2.5

Explanation:

If you are finding the rate just set up the ratio equation.

6 gallons = $15

6 : 15

6/15

Now you want to find the price of 1 gallon, with x as being the price.

6/15 = 1/x

Cross multiply

6 · x = 1 · 15

6x = 15

Solve x.

x = 15 ÷ 6

x = 2.5
