Justin is driving on a long road trip. He currently has 13 gallons of gas in his car. Each hour that he drives, his car uses up 1.75 gallons of gas. How much gas would be in the tank after driving for 3 hours? How much gas would be left after t hours?
Gas left after 3 hours:
Gas left after t hours:
Gas left after 3 hours: 13 - (1.75 * 3) = 13 - 5.25 = 7.75 gallons
Gas left after t hours: 13 - (1.75 * t)
