Mila is driving on a long road trip. She currently has 9 gallons of gas in her car. Each hour that she drives, her car uses up 0.75 gallons of gas. How much gas would be in the tank after driving for 6 hours? How much gas would be left after tt hours?

Question

Gas left after 6 hours:
Gas left after tt hours:

Answer 1

Gas left after 6 hours: 9 gallons - (0.75 gallons/hour * 6 hours) = 9 gallons - 4.5 gallons = 4.5 gallons

Gas left after tt hours: 9 gallons - (0.75 gallons/hour * tt hours) = 9 - 0.75tt gallons
