Final answer:
The resale value of a car that depreciates at 20% per year will be $7,864 after 5 years, when originally purchased for $24,000. We calculate this by using the exponential decay formula and then rounding to the nearest dollar.
Step-by-step explanation:
To find the resale value of a car after 5 years when it depreciates 20% each year, we can use the formula for exponential decay: V = P(1 - r)^t, where V is the future value, P is the initial principal balance (initial value of the car), r is the rate of depreciation, and t is the time in years.
For this car, the initial value P is $24,000, the annual depreciation rate r is 20% or 0.20, and the time t is 5 years.
Applying these values to the formula, we get:
V = $24,000(1 - 0.20)^5
V = $24,000(0.8)^5
V = $24,000(0.32768)
V = $7,864.32
After rounding to the nearest dollar, the resale value of the car after 5 years is $7,864.
