Problema Solution
The present cost of a car is 9,000. the cost of the car depreciates at the rate of 1,000 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 provided by our tutors
Part A:
f(t) = 9,000 - 1,000t
Part B:
t = 3 years
f(3) = 9,000 - 1,000*3
f(3) = 6,000
The total cost of the car after 3 years is $6,000.
Part C:
If the cost is 500 less than the present cost of 9,000 this means the cost is:
9,000 - 500 = 8,500
then the equation is:
f(t) = 8,500 - 1,000t
t = 5
f(5) = 8,500 - 1,000*5
f(5) = $3,500
The cost of the car after 5 years will be $3,500.
