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 $4000 a month how much profit did the shop make?
How much profit did Jim make from each tire repair? ** From each tire repair, he made 20-5=$<<20-5=15>>15 profit
How much profit did Jim make from repairs? ** So repairs made him a profit of 15*300=$<<15*300=4500>>4500
How much profit did Jim make from the two complex repairs? ** The two complex repairs each made him 300-50=$<<300-50=250>>250 profit
How much profit did Jim make from the two complex repairs? ** So those added 250*2=$<<250*2=500>>500
How much profit did Jim make from everything? ** So his total profit from everything was 4500+500+2000=$<<4500+500+2000=7000>>7000
How much profit did Jim make? ** So he made a profit of 7000-4000=$<<7000-4000=3000>>3000
