The value after 0 years = $ 800The value after 1 year = $600The value after 2 years = $450The value after 3 years = $337.5The value after n years = computer cost at (n-1) year - $\frac{1}{4} (n-1 cost)$

Step-by-step explanation:

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 - ( $\frac{1}{4} (800)$ ) = $600

The value after 2 years = 600 - ( $\frac{1}{4} (600)$ ) = $450

The value after 3 years = 450 - ( $\frac{1}{4} (450)$ ) = $337.5

The value after n years = computer cost at (n-1) year - $\frac{1}{4} (n-1 cost)$
