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

### 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:
 Angie alipata $80 na alilipa $42 kwa mahitaji muhimu, hivyo alikuwa na $80 - $42 = $<<80-42=38>>38 zilizobaki.
Angie alikuwa na $18 zilizobaki baada ya kulipa kodi, hivyo sehemu yake ya kodi ilikuwa $38 - $18 = $20 mwezi huu.
