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

### Instruction:
Lucas' father offers to pay him $2 for each window in the house that he cleans. Each floor of Lucas' house has 3 windows; Lucas lives in a 3-story house. To get Lucas to finish the job faster, his father tells him that he will subtract $1 for every 3 days that pass without Lucas finishing the job. In 6 days, Lucas finishes cleaning all the windows in the house. How much will his father pay him, in dollars?

### Response:
 Lucas anasafisha jumla ya sakafu 3 * madirisha 3/sakafu = <<3*3=9>>9 madirisha.
Hii inamaanisha baba yake Lucas atamlipa $2 kwa kila dirisha, hivyo atamlipa Lucas $2/dirisha * 9 madirisha = $<<2*9=18>>18.
Kwa kuwa Lucas alitumia siku 6 kusafisha madirisha, baba yake atapunguza 6 siku / 3 siku = <<6/3=2>>2 mara ya punguzo la $1. Hii inamaanisha baba yake Lucas atapunguza $2 * $1 = <<2*1=2>>2.
Jumla, Lucas atalipwa $18 - $2 = $<<18-2=16>>16.
