Answer: Department 3 had the greatest contribution to overhead of $362,000
Step-by-step explanation:
Contribution to overhead = Sales - Cost of Goods sold - Direct expense
Department 1:
= 1,140,000 - 714,000 - 114,000
= $312,000
Department 2:
= 540,000 - 164,000 - 54,000
= $322,000
Department 3:
= 840,000 - 314,000 - 164,000
= $362,000
