The graphs below represent cost behavior patterns that might occur in acompany's cost structure. The vertical axis represents total cost, and thehorizontal axis represents activity output.
Required:For each of the following situations, choose the graph from the group a-1 that best illustrates the cost pattern involved. Also, for each situation,identify the driver that measures activity output.

- The management of Hartman Company is trying to determine the amount of each of two products to produce over the coming planning period. The following information concerns labor availability, labor utilization, and product profitability: a. Develop a linear programming model of the Hartman Company problem. Solve the model to determine the optimal production quantities of products 1 and 2. b. In computing the profit contribution per unit, management does not deduct labor costs because they are considered fixed for the upcoming planning period. However, suppose that overtime can be scheduled in some of the departments. Which departments would you recommend scheduling for overtime? How much would you be willing to pay per hour of overtime in each department? c. Suppose that 10, 6, and 8 hours of overtime may be scheduled in departments A, B, and C, respectively. The cost per hour of overtime is 18 in department A, 22.50 in department B, and 12 in department C. Formulate a linear programming model that can be used to determine the optimal production quantities if overtime is made available. What are the optimal production quantities, and what is the revised total contribution to profit? How much overtime do you recommend using in each department? What is the increase in the total contribution to profit if overtime is used?arrow_forwardRefer to Problem 8.40 for data. Required: 1. Run a multiple regression equation using machine hours, number of setups, and number of purchase orders as independent variables. Prepare a flexible budget for overhead for the 12 months using the results of this regression equation. (Round the regression coefficients to the nearest cent and predicted overhead to the nearest dollar.) Which flexible budget is betterthe one based on simple regression (with machine hours as the only independent variable) or the one based on multiple regression? Why? 2. Now, suppose that the controller remembers that the factory throws two big parties each year, one for the 4th of July and the other for Christmas. Rerun the multiple regression with machine hours, number of setups, and number of purchase orders, and add a dummy variable called Party. (This variable takes the value one for months with a factory-sponsored party, and zero otherwise.) Prepare a flexible budget for the 12 months using the results of this regression. Discuss the implications of using this new regression for decision making.arrow_forwardLet S represent the amount of steel produced (in tons). Steel production is related to the amount of labor used (L) and the amount of capital used (C) by the following function: S=20L0.30C0.70. In this formula L represents the units of labor input and C the units of capital input. Each unit of labor costs 50, and each unit of capital costs 100. a. Formulate an optimization problem that will determine how much labor and capital are needed to produce 50,000 tons of steel at minimum cost. b. Solve the optimization problem you formulated in part (a). (Hint: When using Excel Solver, start with an initial L 0 and C 0.)arrow_forward
- 1. Top-down versus bottom-up estimates. pts. a. Describe the methods and uses of each of the approaches. 2. Compare the advantages and disadvantages of each of the approaches. 3. What are the three types of costs discussed in the text? Define them. 4. For a small project requiring 120 hours at $50/hr and having a direct overhead rate of 40%, calculate the direct cost (Exercise 1 in Chapter 5). To that add indirect costs (G&A) at 20% and then profit at 20% for a total project price. What are the estimated costs for: Design Programming In-house testing Which “approach to estimating” is this? What weaknesses are inherent in this approach? 5. Take another look at Exercise #5. Use Exercise Figure 5.1 on page 160. But now you are asked to do a bottom-up estimate based on the following data and compare it with the top-down estimate of $800,000. If confronted with these two estimates, what, if any, actions would you take? Deliverables Estimated Hours Rate:…arrow_forwardFanning Academy is a profit-oriented education business. Fanning provides remedial training for high school students who have fallen behind in their classroom studies. It charges its students $730 per course. During the previous year, Fanning provided instruction for 1,000 students. The income statement for the company follows: Revenue Cost of instructors Overhead costs Net income $ 730,000 (434,000) (232,500) $ 63,500 The company president, Andria Rossi, indicated in a discussion with the accountant, Sam Trent, that she was extremely pleased with the growth in the area of computer-assisted instruction. She observed that this department served 300 students using only three part- time instructors. In contrast, the classroom-based instructional department required 28 instructors to teach 700 students. Ms. Rossi noted that the per-student cost of instruction was dramatically lower for the computer-assisted department. She based her conclusion on the following information: Fanning pays its…arrow_forwardAlmed Products has determined that the number of machine hours worked (MH) drives the amount of manufacturing overhead incurred (MOH).
