A total of "2,140'hours of welding time is available annually on the machine. Because each drum requires 0.4 hours of welding machine time, annual production is limited to 5,350 drums. At present, the welding machine is used exclusively to make the WVD drums. The accounting department has provided the following financial data concerning the WVD drums: WVD Drums Selling price per drum $ 177.00 Cost per drum: Direct materials $ 52.10 Direct labor ($25 per hour) 5.00 Manufacturing overhead 8.70 Selling and administrative expense 31.20 97.00 Margin per drum $ 80.00 Management believes 6,275 WVD drums could be sold each year if the company had sufficient manufacturing capacity. As an alternative to adding another welding machine, management has considered buying additional drums from an outside supplier. Harcor Industries, Incorporated, a supplier of quality products, would be able to provide up to 4,350 WVD-type drums per year at a price of $159 per drum, which TufStuff would resell to its customers at its normal selling price after appropriate relabeling. Megan Flores, TufStuff’s production manager, has suggested that the company could make better use of the welding machine by manufacturing bike frames, which would require only 0.5 hours of welding machine time per frame and yet sell for far more than the drums. Megan believes that TufStuff could sell up to 1,740 bike frames per year to bike manufacturers at a price of $274 each. The accounting department has provided the following data concerning the proposed new product: Bike Frames Selling price per frame $ 274.00 Cost per frame: Direct materials $ 103.60 Direct labor ($18 per hour) 40.00 Manufacturing overhead 43.00 Selling and administrative expense 53.40 240.00 Margin per frame $ 34.00 The bike frames could be produced with existing equipment and personnel. Manufacturing overhead is allocated to products on the basis of direct labor-hours. Most of the manufacturing overhead consists of fixed common costs such as rent on the factory building, but some of it is
