You can put this solution on YOUR website!
Well for this one you can go ahead and list each yearly value of the computer, taking half its value each year:
$4000, $2000, $1000, $500, $250, $125, $62.50
So you can see that after six years, its value is under $100.
In general, you would use exponents and/or logarithms to solve a problem such as this.
