Question

The selling price of a car is $18,000. Each year, it loses 15% of its value. Find the exponential function that gives the value of the car t years after its purchase. Write your answer in the form f(t)=a(b)t.

Answer 1

Answer:

f(t)=18,000(0.85)^t

Step-by-step explanation:

18,000 is the a value, and since it is depreciating 15% becomes -.15

so we are going to set it up like f(t)=18,000(1-0.15)^t

Final answer is f(t)=18,000(0.85)^t
