1. Problem #1 a. Perform the profit optimization analysis using the break-even (PE) solution with the following data: (1) fixed costs $7,893, . (2) revenue $50.00 (3) variable cost per unit $1.3. b. The student will assume that this data comes from the company. c. You must use excel or excel gm to be able to solve the exercise. 2. Problem #2 a. A consultant hired by the company you work for includes, as part of his research, assumptions of a daily loss of 600 minutes in personal calls. These calls are estimated at a cost of $0.50 per minute and a salary of $25.00 per hour for the operators who are recruited to track the calls. calls. There are currently 4 female operators. b. Instructions: . You must create a table in which you can make the relevant comparisons that you understand to determine how many operators are needed. Determine the economic principle that you would establish and how much the company would be paying for the first operator, the company would be paying for the first operator. Make the corresponding graph. Personal call cost Marginal profit Payroll cost #of operators 0 1 2 3 4 time lost 600 480 410 370 350 60 35 20 10 3. Problem #3 a. T&H Productions had total costs for the previous month of $18,350.00 for a total production of 500 units of "X" product. total production of 500 units of "X" product. If the company recorded 60% of total costs as variable costs, then determine its average variable cost for that month. (Value 5 points if the answer is correct - 0 points if it is incorrect). incorrect) b. If when 4 units are produced, the total cost is 0.00, and when 5 units are produced, the total cost is $850.00. 5 units, the total cost is $867.00. Determine the marginal cost. (Value 5 pts. - O pts. if incorrect)
