Donald went to a computer store. He saw a 15% reduction in the price of the laptop he wants to buy. If the laptop originally costs $800, how much will he pay for the laptop?

How much was the laptop originally? ** There was $800 x 15/100 = $<<800*15/100=120>>120.
How much will Donald pay for the laptop? ** Thus, Donald will pay $800 - $120 = $<<800-120=680>>680.
#### 680
