gas left after 5 hours:
gas left after t hours:

Explanation:

Step1: Calculate gas used in 5 hours

Gas used per hour is 0.75 gallons, so in 5 hours, gas used is $0.75\times5 = 3.75$ gallons.

Step2: Find gas left after 5 hours

Initial gas is 13 gallons, so gas left is $13 - 3.75 = 9.25$ gallons.

Step3: Find gas left after t hours

Gas used in t hours is $0.75t$ gallons, so gas left is $13 - 0.75t$ gallons.

Answer:

Gas left after 5 hours: 9.25 gallons
Gas left after t hours: $13 - 0.75t$ gallons
