Alicia buys a new car for $20,000. The value of the car decreases by 15% each year.

In about how many years will the value of the car be $10,440?

 

4 years

5 years

6 years

7 years

15% of $20,000 is $3,000 so... subtracting $3,000 a year it would be closer to 4 years than any of the others

20,000 (1-.15)^x  =  10440

.85^x = 10440/20000

x log(.85) = log(10440/20000)

x = 4.00 years
