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

### Instruction:
Mary is paying her monthly garbage bill for a month with exactly four weeks. The garbage company charges Mary $10 per trash bin and $5 per recycling bin every week, and Mary has 2 trash bins and 1 recycling bin. They're giving her an 18% discount on the whole bill before fines for being elderly, but also charging her a $20 fine for putting inappropriate items in a recycling bin. How much is Mary's garbage bill?

### Response:
 Kwanza tafuta gharama ya kila wiki kwa vyombo vya taka: $10/chombo cha taka * vyombo vya taka 2 = $<<10*2=20>>20
Kisha ongeza gharama hii kwa gharama ya chombo cha kuchakata: $20 + $5 = $<<20+5=25>>25
Kisha mara kwa gharama ya wiki kwa idadi ya wiki kwa mwezi: $25/wiki * wiki 4/mwezi = $<<25*4=100>>100/mwezi
Sasa hesabu punguzo la wazee la Mary: 18% * $100 = $<<18*.01*100=18>>18
Sasa toa punguzo na ongeza faini kupata gharama jumla ya kila mwezi: $100 - $18 + $20 = $<<100-18+20=102>>102
