16. Ongchan Metal Fabricators has a diverse product line and a complex cost structure, with some jobs requiring much labor and little machine use and others requiring the opposite mix. Because no single base for a predetermined overhead rate will provide Ongchan Metal management with reliable product cost information, overhead is classified into two cost pools and two predetermined overhead rates are used. For 2001, it is estimated that total overhead costs will consist of P200,000 of overhead related to the usage of direct labor hours and P300,000 of overhead related to machine usage. Total machine usage is expected to be 4,000 hours for the year, and total direct labor hours are expected to be 16,000. Job 345 required P2,000 of direct material, 30 hours of labor at P10 per hour, and 10 hours of machine time. Determine the dual predetermined overhead rates: Per Direct Labor Hour Per Machine Hour a. b. P 3.75 375.00 12.50 12.50 P75.00 7.50 12.50 75.00 c. d. (Adapted) 17. Using the same information in No. 16, compute the cost of Job 345: a. c. P2,300.00 3,162.50 P3,425.00 5,800.00 b. d. (Adapted)
