1. Given the Selling price/unit = $8, the Variable cost/unit = $4, Fixed Costs of $50,000; calculate the: 1. Break-even point in units 2. Break-even point in dollars. 3. The profit at 100,000 units. 4. Draw an X-Y coordinate graph using the form Y = mx + b; or in a break-even format: Net Profit = (Selling Price/unit - variable cost/unit) * total units sold - Fixed Cost (Reference problem on page 293 of textbook, however the graph will be different than the one in the book). 2.1. Formulate and solve this linear programming production-mix situation; in other words, set up the: a. Objective function (maximize profit) b. The two constraints c. Solve best optimal combination of fans and air conditioners. 2. What is the profit at the optimal combination of fans and air conditioners?
