I am buying a used vehicle. I want an equation that will allow me to compare two vehicle's value that are identical in every way except price and mileage. For example:
Car A: $20395 cost and 83400 miles
Car B: $17090 cost and 10500 miles
Car C: $24000 cost and 39000 miles
Miles: lower miles = good
Cost: higher cost = bad
What is a ratio/equation that can produce a number to compare these two variables across vehicles?
