Answer:

  • 37148 +15000n
  • 97148

Step-by-step explanation:

Let n represent the number of years of ownership. Then the number of miles driven is expected to be 15000n at the end of n years. This, added to the odometer reading when the car was purchased, will give the odometer reading at the end of year n:

  37148 +15000n

__

For n=4, this evaluates to ...

  37148 +15000·4 = 37148 +60000 = 97148
