The function f(x) = 3x + 5,000 represents the amount of money a cell phone screen is being sold for, where x is the number of screens being manufactured. The function g(x) = 20x − 400 represents the cost of production, where x is the number of screens being manufactured. What is (f − g)(200)? Explain. $2,000 is the profit made from 200 cell phone screens. $9,200 is the profit made from 200 cell phone screens. $2,000 is the cost of manufacturing 200 cell phone screens. $9,200 is the cost of manufacturing 200 cell phone screens.
