You can put this solution on YOUR website!
first you have to divide 900 by 6 and get 150. which means it went down $150 a month. then since 2 more months pass and the computer costs only 750 that means after 6 months it cost 1050. and then you add the 900 it went down to get that the computer origionally cost $1950.
