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.

Part A

The formula to be used is as shown below:

Where FV=Future Value

PV=Present Value

r=rate, n= number of years

Part B

In our case, PV=20000, r=15%=0.15, n=5

Thus applying this in the formula we get:

Part C

The value of car after 5 years will be $ 8874.1

Part D

Yes, this this answer makes sense compared to the original cost of the car. This is because the depreciation at the rate of 15% per year will bring down the cost of the car substantially over a period of 5 years. The usage of the car and wear & tear all contribute significantly to the depreciation in value of the car from $20000 to $8874.1

Part E

We can draw the graph by taking the x axis as the number of years till 5 and the y axis as the value of the car at each of those years. We can then marks the corresponding points and join them.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

what are the statements
