Question 206040: hello, I have a question on linear equation that models the following situation:
The World of Frying Pans buys a computer for 4000 dollars. After 3 years the computer will be worth 400 dollars. What is the linear equation that relates the value of the computer(V) to the age of the computer(a)?

Answer by Earlsdon(6294) (Show Source): You can put this solution on YOUR website!
The initial value of the computer is given as $4,000.00
In 3 year's time, its value is reduced to $400.00, so it has lost $3,600.00 ($4,000.00-$400.00), so the annual loss (L) as a linear function is:

dollars per year.
If a is the number of years, then the linear function that relates the value of the computer (V) to the age of the computer (a) in years is just:
