The cost of computer = $ 800
It losed 1/4th of value every year.
The value of computer after 0 years = cost of computer = $ 800
The value after 1 year = 800 - (
) = $600
The value after 2 years = 600 - (
) = $450
The value after 3 years = 450 - (
) = $337.5
The value after n years = computer cost at (n-1) year -![\frac{1}{4} (n-1 cost)](/tpl/images/0588/0682/f179d.png)
