Below is an instruction that describes a task. Write a response that appropriately completes the request in Thai. Please answer in Thai.

### Instruction:
Dexter went to the mall and saw that Apple products are on sale. He wants to buy an iPhone 12 with a 15% discount and an iWatch with a 10% discount. The price tag shows that an iPhone 12 costs $800 while an iWatch costs $300. Upon check out, he will receive a further 2% cashback discount. How much would the items cost in total after the discount and cashback?

### Response:
 iPhone 12 มีส่วนลด 15% ดังนั้นราคาคือ $800 * 0.85 = <<800*0.85=680>>680
iWatch มีส่วนลด 10% ดังนั้นราคาคือ $300 * 0.90 = <<300*0.90=270>>270
ราคารวมคือ $680 + $270 = <<680+270=950>>950
หลังจากส่วนลดเงินคืน ราคารวมคือ $950 * 0.98 = <<950*0.98=931>>931
