Exercise 17-17 Activity-based costing LO P3 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 $ 9,700 6,200 18,600 $34,500 10,700 ft. $ 3.22 Squared Edge Total $21,400 $ 31,100 12,000 18,200 36,000 54,600 $69,400 $ 103,900 14,200 ft. $ 4.89 Glassworks's controller wishes to apply activity-based costing (ABC) to allocate the $54,600 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 $ 2,184 29,160 23, 256 $ 54,600 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 $6,200 200 hours 30 times Squared Edge $12,000 800 hours 93 times Total $18, 200 1,000 hours 123 times Required: 1. Assign these three overhead cost pools to each of the two products using ABC.
