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

### Instruction:
Dakota and Ben order eggs for $3, pancakes for $2, and 2 mugs of cocoa for $2 each. The tax is $1. Later, Ben then decides to order 1 more batch of pancakes and 1 more mug of cocoa as he is still hungry. How much change should they get from $15?

### Response:
 ยอดรวมเดิมคือ $3 + $2 + $2 + $2 + $1 = $<<3+2+2+2+1=10>>10
เบนเพิ่มยอดรวมเป็น $10 + $2 + $2 = $<<10+2+2=14>>14
พวกเขาควรได้รับเงินทอน $15 - $14 = $<<15-14=1>>1
