He manages to build 60 computers a month. He has to pay $5000 a month in rent and another $3000 in non-rent extra expenses a month. How much profit does he make a month?
<bot>: How much does each computer sell for? ** He sells each computer for 1.4*800=$<<1.4*800=1120>>1120
How much profit does he make per computer? ** That means he makes a profit of 1120-800=$<<1120-800=320>>320 per computer
How much money does John make from selling computers? ** So he makes 320*60=$<<320*60=19200>>19200 from selling computers
How much does John have in extra expenses? ** He has extra expenses of 5000+3000=$<<5000+3000=8000>>8000 a month
How much profit does John make a month? ** So his profit is 19200-8000=$<<19200-8000=11200>>11,200
