Question:

Shelby Electronics manufactures two large-screen television models: the Prime, which sells for $1,600, and a new model, the Deluxe, which sells for $1,300. Few per unit cost data are given:
Traditional Costing Prime Deluxe
DM $700 $420
DL ($20 per hour) $120 $100
MOH ($38 per DLH) $228 $190
In 2019, Shelby manufactured 25,000 units of the Prime and 10,000 units of the Deluxe. The overhead rate of $38 per direct labor hour was determined by dividing total expected manufacturing overhead of $7,600,000 by the total direct labor hours (200,000) for the two models.
Under traditional costing, the gross profit on the models was Prime $552 or ($1,600 - $1,048), and Deluxe $590 or ($1,300 - $710). Because of this difference, management is considering phasing out the Prime model and increasing the production of the Deluxe model.
Before finalizing its decision, management asks Shelby’s controller to prepare an analysis using activity-based costing (ABC). The controller accumulates the following information about overhead for the year ended December 31, 2019.
