b) how many miles per gallon did the car get?
This is another problem that needs to be worked out.
Answer
To get the number of miles that she drove take the ending value on the odometer -
start value on the odometer. This is 15665.6 - 15,345.4 = 320.2.
The amount of gas that it took to get this far was 13.4 gallons.
This means the mileage would be 320.2/13.4 = 23.9 mpg.
