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

### Instruction:
John needs to replace his shoes so he decides to buy a $150 pair of Nikes and a $120 pair of work boots.  Tax is 10%.  How much did he pay for everything?

### Response:
 รองเท้าราคา $150 + $120 = $<<150+120=270>>270
ภาษีมูลค่าเพิ่มคือ $270 * .1 = $<<270*.1=27>>27
ดังนั้นราคารวมทั้งหมดคือ $270 + $27 = $<<270+27=297>>297
