4. You have joined Unilever Bangladesh as an intern in the finance division. Your first project as an intern will be to help the junior finance manager of Unilever Bangladesh, Mr. Reza Monem, to help in his flexible budget performance appraisal of the consumer products division for year ended December 31, 2021. The cost for the current year's planning budget appears below. Unilever Bangladesh planned to sell 5 different types of products and Mr. Monem estimated that total 60 machine hours will be required to produce those products. Unilever Bangladesh Costs from the Planning Budget For the Year Ended December 31 Budgeted number of productions 5 Budgeted machine hours 60 Supervisory salaries Tk. 144,000 Gasoline expenses 27,000 Maintenance expenses 10,800 Supplies 43,000 Factory space rent 45,000 Utilities expenses 10,500 Machine Setup expenses 13,000 Administrative expenses 43,200 Total Tk. 336,500 You have observed that some of the costs vary with the number of productions, some with the machine hours, and some are fixed and depend on neither the number of productions nor the machine hours. The costs of supplies, and machine setup vary only with the number of productions. On the other hand, supervisory salaries, gasoline, and maintenance expenses vary with the machine hours. Similarly, factory space rent and utilities expenses will vary with the machine hours. Administrative expenses are more difficult to pin down, but the best estimate is that approximately 75% of the budgeted costs are fixed, 15% depend on the number of productions, and the remaining 10% depend on the machine hours.
