Exercise 17-14 Activity-based costing LO P3 A2 Glassworks Inc. produces two types of glass shelving, rounded edge and squared edge, on the same production line. For the current period, the company reports the following data. Direct materials Direct labor Overhead (300% of direct labor cost) Total cost Quantity produced Average cost per ft. (rounded) Rounded Edge $ 9,400 6,100 18,300 $33,800 10,400 ft. $ 3.25 Squared Edge Total $21,600 $ 31,000 12,000 18,100 36,000 54,300 $69,600 $ 103,400 14,100 ft. $ 4.94 Glassworks's controller wishes to apply activity-based costing (ABC) to allocate the $54,300 of overhead costs incurred by the two product lines to see whether cost per foot would change markedly from that reported above. She has collected the following information. Cost Overhead Cost Category (Activity Cost Pool) Supervision Depreciation of machinery Assembly line preparation Total overhead $ 2,172 29,000 23, 128 $ 54,300 She has also collected the following information about the cost drivers for each category (cost pool) and the amount of each driver used by the two product lines. (Round activity rate and cost per unit answers to 2 decimal places.) Usage Overhead Cost Category (Activity Cost Pool) Supervision Depreciation of machinery Assembly line preparation Driver Direct labor cost ($) Machine hours Setups (number) Rounded Edge $6,100 200 hours 32 times Squared Edge $12,000 700 hours 94 times Total $18,100 900 hours 126 times Required: 1.
