How to determine the smallest absolute value

The absolute value is basically the distance from zero, and distance is ALWAYS positive. After you removed your negatives, you need to just compare the values. For example. The smallest absolute value between -27 and 19 is 19. Hope this helped!

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 -

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 - ( ) = $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 -
