Question 1029259
Latoya 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 
9%
per year, and for the laptop it was 
7%
per year. The total finance charges for one year were 
$365
. How much did each computer cost before finance charges? 
------------------------
Value Eq:: C = L + 300
Interest Eq::9C + 7L = 36500
=======
Modify for elimination::
9C - 9L = 9*200
9C + 7L = 36500
-----------------------
16L = 34700
Laptop cost = $2168.75
Computer cost:: subtract $300
