Eric brought a laptop for $664. It was marked $50 of because it was an opened product. He also got a 15% discount, which was taken off the original price what was the original price of the laptop.
Interest per period (period = month) = .06 / 12 periods = 12
6500 (1 + .06/12)12 = $ ................
Laptop 15% off means you pay 85% then take $ 50 off
x(.85) - 50 = $ 664 solve for 'x' the original price
