Question

A manager wishes to predict the annual cost (y) of an automobile based on the number of miles (x) driven. The following model was developed:

y = $1500 + 0.36x.
If a car is driven 15000 miles in a year, the model predicts the annual cost of the car to be ____.

Answer 1

If a car is driven 15,000 miles in a year, the model predicts the annual cost of the car to be $ 6,900.

Explanation:

The model developed is:

y = $ 1,500 + 0.36x, where:

y represents the annual cost of an automobile

x represents the number of miles driven

If x = 15,000, let's solve for y:

y = 1,500 + 0.36x

y = 1,500 + 0.36 * 15,000

y = 1,500 + 5,400

y = 6,900
