Question

4. You buy a used car with 37,148 miles on the odometer. Based on your regular driving habits, you plan to drive the care about 15,000 miles each year that you own it. Write and expression for the number of miles that appears on the odometer at the end of each year. Use the expression to find the number of miles that appear on the odometer after you have owned the car for 4 years.

Answer 1

• 37148 +15000n
• 97148

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
