Rachel's parents live on a farm. Her mother decided to try and make it a working farm. She raised 60 goats, then entered into a series of business transactions. She traded all the goats for sheep at an exchange rate of 5 goats for 7 sheep. Next, she exchanged all the sheep for hogs at a rate of 4 sheep for 2 hogs weighing 250 lbs. each. She sold all the hogs at a market price of $55.00 per 100.0 lbs. How much money did she make from the 60 goats?
