Lambda Manufacturing produces two types of watches: smart and digital. The watches are produced using one continuous process. Four activities have been identified: machining, setups, receiving, and packing Resource drivers have been used to assign costs to each activity. The overhead activities, their costs, and the other related data are as follows: Product Machine Hours Setys Receiving Orders Packing Orders Smart 12,000 200 300 SOO Digital 12,000 800 700 2,500 Costs 590,000 $50,000 $10,000 $30,000 Calculate the total overhead assigned to the smart watches, using only machine hours to calculate a plantwide rate. (Note: Round the plantwide rate to two decimal places) O $117,000 $90,000 $63,000 O $45,000
