Question 1161167: Nicole bought a desktop computer and a laptop computer. Before finance charges, the laptop cost $
300 more than the desktop. She paid for the computers using two different financing plans. For the desktop, the interest rate was
6% per year, and for the laptop it was
7% per year. The total finance charges for one year were $398
. How much did each computer cost before the finance charges? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! interest=prt
for desktop it is p*.06*1=.06p
for laptop it is (p+300)*.07*1=.07p+21
Those two add to $398
so .13p+21=398
.13p=377
p=$2900 for desktop and that is $174 interest
=$3200 for laptop and that is $224 interest
