Answer:
The car will have lost it's total value by 2007.
Step-by-step explanation:
If initially the car was valued at 44,000$, and after 9 years it's value dropped to 15,000$, we can say that the car's value dropped in 29,000$. If we suppose that the drop is the same every year, we can say that it was of 3,222,2$ by each year.
This amount of money is the 7,3% of the initial value of the car (I multiplied 3,222,2 x 100 : 44,000).
a) The annual rate of change was of 7,3%.
b) There are 14 years between 1993 and 2007. If we multiply 7,3% by 14, we get that the car lost 102,2% of it's initial value.
