You have 1/4 of a tank of gas and 10 dollars in your wallet. Gas is $2.50/gallon and your car holds 13 gallons. Explain how you would find out how many total gallons you have in your car after you put $10 worth of gas.

Respuesta :

1. Find how much gas can be obtained: $10 goes into $2.50 4 times, so you can get 4 gallons.

2. Find how much gas is in the car: 1/4 of the maximum 13 gallons is 3.25 gallons, so there is already 3.25 gallons in your car.

3. Find how many gallons you have total: 4 gallons + 3.25 gallons =

7.25 gallons
