### Instruction:
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?

### Response:
 มีเงินลด $800 x 15/100 = $<<800*15/100=120>>120
ดังนั้น ดอนัลด์จะต้องจ่ายเงิน $800 - $120 = $<<800-120=680>>680.
