For a certain company, the cost for producing .1: items is 553: + 300 and the revenue for selling :1: items is 95:1: 0.53:2. The prot that the company makes is how much it takes in (revenue) minus how much it spends (cost). In economic models, one typically assumes that a company wants to maximize its prot, or at least wants to make a prot! Part a: Set up an expression for the prot from producing and selling as items. We assume that the company sells all of the items that it produces. (Hint: it is a quadratic polynomial.) Part b: Find two values of :1: that will create a prot of $50. The eld below accepts a list of numbers or formulas separated by semicolons (e.g. 2; 4; 6 or a: + 1; :1: 1). The order of the list does not matter. To enter 5, type sqrt(a)
