Mr. keller bought a car for $20,000. a study shows that a car will depreciate (go down in value) by 15% each year. how much is mr. keller’s car worth after 5 years? a) formula used: b)substitute values: c) final answer d) does this final answer make sense compared to the original cost of the car? why? e) describe (using a complete sentence or two) how you can solve this problem graphically. answer all

AnswerA: the formula would be f(x) = P(R) ^T or f(x) = Principle(rate)^time

B: f(x) = 20,000(0.85)^5  

C: = 8,874.10625

D: Yes, the final answer makes sense compared to the origional cost of the car in relation to the formula. As well, time decreases the value of a car, so for the cost to be so low only makes sense due to the cars decrease in value or an extended and elongated amount of time.

E: You can solve this equation graphically by plotting th point at 20,000 and then taking 85% of 20,000 and plotting it each time until you get to the fifth year.
