Percentage of depreciation of the car that Marie bought = 15% Present value of the car = 13000 Let us assume that the value of the car at the time of buying = x So The percentage valuation of the car now = (100 - 15) percent = 85 percent Then (85/100) * x = 13000 85x = 13000 * 100 85x = 1300000 x = 1300000/85 = 15294.12 So the actual cost of the car is 15294.12. I hope the procedure is clear enough for you to understand.
