A lawyer charge clients 75$ an hour plus a fixed cost of 350$ to write a contract.Another lawyer charges 100$ an hour plus a fixed cost of 200$.For how many hours of work do the lawyers charge the same amount.
Let h be the hours at which their charges haromnize, so we have:
75h + 350=100h + 200 we gather like terms on one side
350 - 200=100h - 75h
150=25h we divide both sides by 25
h=6 hours at which their charges will be equal.
