Question 182162
You didn't ask a question. Figure what out?
Are you looking for the value of the copier for each year?
Hopefully something here will help.
Look at final (salvage) value versus initial value. 
{{{DELTA*V[t]=12000-2000=10000}}}
Typically you depreciate linearly so each of the four years the value will be reduced by,
{{{ DELTA*V=10000/4=2500}}}
On Jan. 1, 2008, the copier's value is $12000.
On Jan. 1, 2009, the copier's value is $9500.
On Jan. 1, 2010, the copier's value is $7000.
On Jan. 1, 2011, the copier's value is $4500.
On Jan. 1, 2012, the copier's value is $2000.
