The value of a car depreciates each year. Suppose that you purchased a car for $21,000 and the value of the car depreciates by 12% each year.
Determine the following: Initial value of the car: dollars
A.) 1-year growth factor:
B.) 1-year percent change: %
C.) Define a function f f that determines the value of the car in terms of the number of years since the car was purchased, x
D.) Determine the value of the car 8 years after it was purchased. (You may round your answer to the nearest penny).
Solution
A) 1-year growth factor=(1-(12/100))
1-year growth factor=1-0.12
1-year growth factor=0.88
B)1-year percent change: 12%
C)f (x)=21000(1-(12/100))x
f (x)=21000(1-0.12)x
f (x)=21000(0.88)x
D)value of the car 8 years after it was purchased is f(8)=21000(0.88)8
. f(8)=7552.33
value of the car 8 years after it was purchased =$ 7552.33
