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

### Instruction:
Angie is part of a household with shared expenses and contributes $42 a month for necessities. She has a salary of $80 per month. She also pays a share of the household taxes each month. At the end of this month, she had $18 left over. How much did she pay in taxes this month?

### Response:
 แองจีได้รับรายได้ 80 และจ่าย 42 สำหรับความจำเป็น ดังนั้นเธอเหลือ 80 - 42 = $<<80-42=38>>38
เธอจ่ายภาษี 18 เพราะ 38 - 18 = 20.
