Question

A $30,000 car depreciates in value 12% a year. How much will the car he worth in 5 years?

Answer 1

15,831.957504

Explanation:

30,000*.88=26400

26400*.88=23232

23232*.88= 20,444.16

20,444.16*.88= 17,990.8608

17,990.8608*.88= 15,831.957504

Answer 2

100% - 12% = 0.88, so the exponential function that represents this situation is:

f(x) = 30000 * 0.88^x

f(5) = 30000 * 0.88^5

f(5) = $15.831.96
