For a certain company, the cost for producing r items is 55x + 300 and the revenue for selling z items is 952-0.522. The profit 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 profit, or at least wants to make a profit! Part a: Set up an expression for the profit from producing and selling 2 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 2 that will create a profit of $300.

For a certain company, the cost for producing a items is 40x + 300 and the revenue for selling x items is 80x – 0.5x². The profit 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 profit, or at least wants to make a profit! Part a: Set up an expression for the profit from producing and selling x 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 that will create a profit of $50. The field below accepts a list of numbers or formulas separated by semicolons (e.g. 2; 4; 6 or x + 1; x – 1). The order of the list does not matter. To enter va , type sqrt(a).

4. A retailer imports a crate of sunglasses for $3800. There are x amount of pairs of glasses in the box. 8 pairs of glasses are defective and can't be sold. The retailer sells the remaining sunglasses for $4800, realizing a profit of $6 per pair. Write the equation that represents this scenario.

3x+5-x=x-3
