In addition, the direct labor hours (dlh) used to produce a unit of each product in each department were determined from engineering records, as follows: Production Departments Gasoline Engine |Diesel Engine Fabrication Department 2.8 dlh 1.9 dlh Assembly Department 1.9 2.8 Direct labor hours per unit 4.7 dlh 4.7 dlh a. Determine the per-unit factory overhead allocated to the gasoline and diesel engines under the single plantwide factory overhead rate method, using direct labor hours as the activity base . If required, round all per-direct labor hours and per-unit answers to the nearest cent. Gasoline engine $378.07 per unit Diesel engine $378.07 / per unit A) 812,400.00 / 10,100 = 80.44 *4.7 = 378.07 b. Determine the per-unit factory overhead allocated to the gasoline and diesel engines under the multiple production department factory overhead rate method, using direct labor hours as the activity base for each department. If required, round all per-unit answers to the nearest cent. Gasoline engine $402.00 V per unit Diesel engine $345.30 V per unit Points: 212 B) Gasoline - 111 * 2.8 + 48 * 1.9 = 402 C) Diesel - 111 * 1.9 + 48 * 2.8 = 345.3
