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

### Instruction:
Jim decides to open up a bike shop.  The most common repair he does is fixing bike tires.  He charges $20 for this and it cost him $5 in parts.  In one month Jim does 300 of these repairs.  He also does 2 more complex repairs for $300 each and cost $50 in parts.  He also sells $2000 profit worth of things from his retail shop.  If rent and other fixed expense for the shop is $4000 a month how much profit did the shop make?

### Response:
 Kutoka kwa kila marekebisho ya tairi, alipata faida ya 20-5=$<<20-5=15>>15
Hivyo, marekebisho yalimpatia faida ya 15*300=$<<15*300=4500>>4500
Marekebisho mawili yenye utata zaidi kila moja yalimpatia faida ya 300-50=$<<300-50=250>>250
Hivyo, yalimuongezea faida ya 250*2=$<<250*2=500>>500
Hivyo, jumla ya faida yake kutoka kila kitu ilikuwa 4500+500+2000=$<<4500+500+2000=7000>>7000
Hivyo, alipata faida ya 7000-4000=$<<7000-4000=3000>>3000
