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

### Instruction:
Mark got a 5% raise at his job.  Before the raise, he earned 40 dollars per hour.  He works 8 hours per day for 5 days per week.  His old bills used to be 600 dollars a week but he decided to add a hundred dollar a week personal trainer.  How much does he have leftover a week?

### Response:
 Alipata ongezeko la dola 40 * 0.05 = $2 kwa saa
Hivyo anapata $40 + $2 = $42 kwa saa
Anafanya kazi masaa 8 kwa siku hivyo anapata $42 * 8 = $336 kwa siku
Anafanya kazi siku 5 kwa wiki hivyo anapata $336 * 5 = $1680 kwa wiki
Matumizi yake baada ya kuongeza mwalimu binafsi ni $600 + $100 = $700 kwa wiki
Hivyo anabakiwa na $1680 - $700 = $980 kwa wiki
