Suppose the value of a car depreciates 8% every year. To the nearest dollar, what will a car that cost $23,995 be worth after 5
Vanyuwa [196]

Answer:

<em>The car will worth $15815 after 5 years.</em>

Step-by-step explanation:

The formula is:    A=P(1+r)^t, where P = Initial cost, A = Final cost,  r = Rate of change in cost per year and  t = Number of years.

Here, P= 23995, t= 5

and r= 8\%=0.08

As here the <u>value of the car depreciates every year, so we need to plug the value of r as negative</u>. So, r=-0.08

Now plugging the above values into the formula, we will get.....

A=23995(1-0.08)^5\\ \\ A=23995(0.92)^5\\ \\ A=15814.6611... \approx 15815

<em>(Rounded to the nearest dollar)</em>

So, the car will worth $15815 after 5 years.
