Question

The cost to own and operate a car depends on many​ factors, including gas​ prices, insurance​ costs, size of​ car, and finance charges. Using a cost calculator found on the​ Internet, the owner determined it costs him approximately ​$0.684 per mile to own and operate a car. The total cost is a function of the number of miles driven and can be represented by the function Cequals0.684m. When the owner finally takes his car to the​ junkyard, the odometer reads 157 comma 200 miles.

What is the output variable?

Answer 1

In the function \( C = 0.684m \), the output variable is \( C \), which represents the total cost to own and operate the car in dollars. The input variable \( m \) represents the number of miles driven. Therefore, as the number of miles \( m \) changes, the total cost \( C \) will change according to the given function.
