Question 1200646: Ryan bought a desktop computer and a laptop computer. Before finance charges, the laptop cost $450 more than the desktop. He paid for the computers using two different financing plans. For the desktop the interest rate was 9% per year, and for the laptop it was 6% per year. The total finance charges for one year were $300. How much did each computer cost before finance charges? Answer by ikleyn(52776) (Show Source):
x dollars for the desktop; (x+450) dollars for the laptop.
Write one year total finance charges equation
0.09*x + 0.06*(x+450) = 300 dollars.
Simplify and find x.
etc.
The rest is simple arithmetic.
