A camera factory has fixed production cost of $50,000 plus $75 for each camera produced.  Its cost of production function can be written as C(x) = 75x + 50,000. 

The company decides to sell each camera for $325, so its revenue function can be written as R(x) =325x.

How many cameras must the company sell at $325 per camera in order to "break even"?
