PLEASE HELP!!!! MEDAL







the present cost of a car is $9,000. The cost of the car depreciates at the rate of $1000 per year.

Part A: Write a function to show the cost of the car f(t) after t years.

Part B:what is the total cost of the car after 3 years?

part C: If the cost of the car was $500 less than the present cost, what would be the cost of the car after 5 years?

Answer 1

Part A:
f(t) = (present cost - total depreciation amount after t years)
Now, present cost is given which is $9000. Let t = number of year after the car was purchased so that the total depreciation amount after t years is 9000t.
Plugging these values into f(t) i have given you, what is the function you get?

Answer 2

9000*3???
