a. $7,000

b. $9,000

Explanation:

The computations are shown below:

a. The equation is

y = 4,000 + 0.20x

where,

X = miles driven

And y = Annual cost

Since 15,000 miles car is driven this year, so the forecasted cost would be

y = 4,000 + 0.20 * 15,000 miles

= 4,000 + 3,000

= $7,000

b. And if the car is driven 25,000 miles, so the forecasted cost would be

y = 4,000 + 0.20 * 25,000 miles

= 4,000 + 5,000

= $9,000

We simply put this miles in the equation above
