So if the cars is purchased in 1990 for five dollars and its value increases by 6% each year you would do : 5$ x 6% = .30 cents. And if its 2017 now its value would be a total of: 27 years of a .30 cent increase each year ... 27 x .30 that would be 8.1$ + 5$ = 13.1$ Im sorry if I am wrong on this didnt get much information based on this question
