There is a formula for this but I can't quite remember what it is. This is another way to find the answer:
First, you have to find what 30% of the original value is.
To find the value, the trick I use is:
[tex] \frac{is}{of} [/tex] = [tex] \frac{percent}{100} [/tex]
You need to know what is 30% of $2280.
You are looking for "is" so in the equation, we can set "is" to x.
The percentage is 30%
And you are trying to find 30% Of $2280 so 2280 is your "of" value.
(Hope that wasn't too confusing)
But now your equation is
[tex] \frac{x}{2280} = \frac{30}{100} [/tex]
When you cross multiply, you get
100x = 2280 * 30
solve for x
100 x = 68400
x = 684
which means that after the first year, the value will depreciate or go down by $684
After one year, the value of the computer is
$2280 - $684 = $1596
Doing the same thing again, this time finding 30% of 1596 = $478.8, you find that after two years, the value is
$1596 - $478.8 = $1117.2
Once again, for the third year, 30% of $1117.2 = $335.16
$1117.2 - $335.16 = $782.04
$782.04 is your final answer
*sorry I couldn't remember the formula but hope this helped at least :)
