Answer:
<u>If a car is driven 15,000 miles in a year, the model predicts the annual cost of the car to be $ 6,900.</u>
Step-by-step 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
<u>y = 6,900</u>
