Respuesta :
An appropriate unit for Abedabun's purpose would have to include $ for the car's maintenance COST and a large distance measurement because we are talking about cars (and they can travel a long distance).
The best answer would be:
C) $/km
$ for the cost and km for the distance the car is driven.
If the cost changes along with the distance a vehicle ahas been droven, the best unit that Abedabun can use is:
$/km
Where:
$ = cost
km = distance driven
Hope it helped,
