A new car is purchased for 16500 dollars. The value of the car depreciates at 5.75% per year. What will the value of the car be, to the nearest cent, after 5 years?

1 answer

To find the value of the car after 5 years of depreciation at a rate of 5.75% per year, we can use the formula for exponential decay:

\[ V = P(1 - r)^t \]

where:

  • \( V \) is the future value of the car,
  • \( P \) is the initial purchase price of the car,
  • \( r \) is the annual depreciation rate (as a decimal),
  • \( t \) is the time in years.

Given:

  • \( P = 16500 \) dollars,
  • \( r = 5.75% = 0.0575 \),
  • \( t = 5 \) years.

Now plug in the values:

\[ V = 16500(1 - 0.0575)^5 \]

Calculate \( 1 - 0.0575 \):

\[ 1 - 0.0575 = 0.9425 \]

Now calculate \( 0.9425^5 \):

\[ 0.9425^5 \approx 0.7354 \quad (\text{using a calculator}) \]

Now substitute this value back into the equation:

\[ V = 16500 \times 0.7354 \approx 12151.10 \]

Finally, rounding to the nearest cent, the value of the car after 5 years will be approximately:

\[ \boxed{12151.10} \text{ dollars} \]
