Katie has $6,500 in her savings account. If it earns 6% interest every month how much money does Katie have in her bank account after half a year? 

 

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

EP: The exponent of 12 in part 1 should be 6, because she wants it for "half a year".
