need answer correct

(25 points) Natalie Corp. manufactures three models of their product-Version A Version B. and Version C Natalie currently allocates manufacturing overhead costs to the three model lines based on direct labor costs a version of traditional absorption costing), and selling prices are set by computing prices that provide for a 30% margin over computed product costs per unit Cost and revenue information follow: Version A Version B Version C Direct materials $14.000 $ 19,000 $27,000 Direct labor 15.000 21,000 30.000 Overhead allocated 47.727 66,818 95.455 Total cost 576.727 $106.818 $152.455 Units 3.000 5.000 9,000 Cost per unit $25.58 $21 36 $16.94 Selling price per unit $33.25 $27.77 $22.02 Natalie is concerned that profits are not as high as they could be. Natalie is considering implementation of an activity-based costing (ABC) system. Overhead costs have been categorized into three cost pools for ABC purposes Setup costs would be allocated using setups as the allocation base engineering costs would be allocated using number of components as the allocation base, and Maintenance costs would be allocated using the number of Maintenance calls as the allocation base The following activity and cost information has been compiled Version A Version B Version Direct labor hours 1200 2000 3100 Setups 36 23 21 Number of components 25 15 10 Number of Maintenance calls 150 180 220 Costs Setups 5 45,000 Engineering 100.000 Maintenance 65,000 Total overhead $210.000 a. Allocate the overhead costs to the three models using activity-based costing and compute the cost per unit for each model b. Provide a possible explanation for why allocating costs based on direct labor costs may have led to the company's overall lack of proftability. Explain one benefit simply more accurate is not sufficient) and one drawback or downside of activity-based costing in comparison with traditional absorption costing
