Question 1110868: Problem Page Sam bought a desktop computer and a laptop computer. Before finance charges, the laptop cost $400 more than the desktop. He paid for the computers using two different financing plans. For the desktop the interest rate was 7% per year, and for the laptop it was 8% per year. The total finance charges for one year were 275 . How much did each computer cost before finance charges? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Let d be the desktop computer, and d+400 be the laptop. Then:
