Gary and Sheryl are STILL discussing driving to visit some relatives who live $682$ miles away. They've already thought about the gas costs. Gary says "but wait, shouldn't we consider the other maintenance on the car? Using it for a long drive changes when you have to make bigger maintenance purchases."

Let's find the potential Maintenance costs that the trip will contribute $-$ this is similar to prorating! $($Hint: find the cost per mile for each item and then multiply by the miles that they will be driving$)$:

General maintenance $($oil and fluid changes$)$: $$34$ every $3,000$ miles

Tires: Tires for the car cost $$640$; they are supposed to be replaced every $70,000$ miles

Repairs: The website

Edmonds.com estimates that repairs on their car will be approximately $$300$ per year; this is based on driving $15,000$ miles ${?}^7$

Total Maintenance cost of driving their own car for the round trip: $

What do you think about this? Would you choose to drive your own car, or rent a car? Why would vou make this choice $-$ is there more to consider besides the cost?
