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

### Instruction:
Paul went to the sporting goods store to buy a tennis racket.  His favorite brand was having a sale that offered customers a deal to buy one racket at full price and get the second racket for half off the full price.   If he purchased two rackets that were each originally marked at a full price of $60, how much did he spend on the two rackets, in dollars?

### Response:
 ราคาครึ่งราคาเต็มของ $60 คือ $60/2=$<<60/2=30>>30 ส่วนลด
หลังจากแร็กเก็ตได้รับส่วนลด $30 ราคาจะเป็น $60-$30=$<<60-30=30>>30.
ดังนั้น แร็กเก็ตสองอันมีราคา $60+$30=$90.
