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

### Instruction:
Casey is trying to decide which employee she wants to hire. One employee works for $20 an hour. The other employee works for $22 an hour, but Casey would also get a $6/hour subsidy from the government for hiring a disabled worker. How much money per week would Casey save by hiring the cheaper employee, if they both work 40 hours per week?

### Response:
 Kwanza tafuta kiasi cha kila saa mfanyakazi wa kwanza anagharimu baada ya ruzuku ya serikali: $22/saa - $6/saa = $<<22-6=16>>16/saa.
Kisha tafuta kiasi ambacho mfanyakazi wa kwanza atagharimu kwa wiki: 40 masaa/kwa wiki * $16/saa = $<<40*16=640>>640/kwa wiki.
Kisha tafuta kiasi ambacho mfanyakazi mwingine atagharimu kwa wiki: 40 masaa/kwa wiki * $20/saa = $<<40*20=800>>800/kwa wiki.
Kisha toa gharama ya kila wiki ndogo kutoka kwa gharama ya kila wiki kubwa ili kupata tofauti: $800/kwa wiki - $640/kwa wiki = $<<800-640=160>>160/kwa wiki.
