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

15 dollars worth of gas /6 gallons of gas = $2.5 per gallon

$2.5 x 1 = $2.5

$2.5 for 1 gallon

Step-by-step explanation:

$2.50

Step-by-step explanation:

We know that 6 gallons of gas costs $15 and we want to find how much one gallon of gas costs so we are going to use ratio's to work the price of one gallon so,

6 gallons = $15

If we divide both sides by 2 then we get

3 gallons = $7.50

If we divide both sides by 3 then we get

1 gallon = $2.50

So 1 gallon of gas is $2.50, we can check this solution is correct because if we multiply $2.50 by 6 we should get $15 so

2.50 × 6 = $15
