24 miles is the answer.
Step-by-step explanation:
The previous reading of Jeremy's car = 25500
The current reading is = 26100
Difference between readings = [tex]26100-25500=600[/tex]
Number of gallons used to fill the tank = 25
So, miles traveled by Jeremy in 25 gallons is = 600
In 1 gallon, he travels = [tex]\frac{600}{25}= 24[/tex] miles.
Therefore, Jeremy's car gets 24 miles per gallon.
