Question

2. Vanessa wants to model how a car's maintenance costs change as the distance someone drives the car increases. What would be an appropriate unit for Vanessa's purpose?

Miles/$

Gallons/Miles

$/Miles

$/Gallons

Answer 1

The answer is $/Miles

Explanation:

• If Vanessa wants to know hoy the car's maintenance costs change as the distance increases, she is analysing the cost of maintaining the car (wich is expressed in dollars , $), when the distance increases (which is measured in miles or metres, or some other distance measure).
• Then, the appropiate units of measure for this problem are dollars (to represent the cost of maintenance) and miles (to represent the distance the car travels).
