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

### Instruction:
Ice cream costs $2.00 and toppings cost $0.50 per topping. How much does a sundae with 10 toppings cost?

### Response:
 ก่อนอื่นให้บวกค่าท็อปปิ้งทั้งหมดกัน: 10 ท็อปปิ้ง * $0.50/ท็อปปิ้ง = $<<10*0.5=5.00>>5.00
จากนั้นให้บวกจำนวนนั้นกับราคาไอศกรีม: $5.00 + $2.00 = $<<5+2=7.00>>7.00
