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

### Instruction:
Irene earns $500 if she works for 40 hours a week and gets an extra $20 for every hour of overtime. If she worked 50 hours last week, calculate her total income.

### Response:
 Ikiwa Irene alifanya kazi masaa 50 wiki iliyopita, anastahili masaa 10 ya ziada.
Kwa kuwa anapata $20 kwa kila saa ya ziada, Irene alipata jumla ya 10*$20 = $<<10*20=200>>200 kwa masaa ya ziada.
Pamoja na mshahara wake wa kawaida, ambao ni $500, kipato chake cha jumla ni $500+$200 = $<<500+200=700>>700
