For a certain company, the cost for producing x items is 45x + 300 and the revenue for selling x items is 85x - 0.5x^2. Part: A: Set up an expression for the profit from selling x items. We assume that the company sells all of the items it produces.

Part B: Find two values of x that will create a profit of $300.
