This would mean outsourcing the manufacturing of accessories such as laptop covers. Due to the quick response times required to meet the demands of Dapple's customer orders, the designer brand manufacturer is proposing to set up a new manufacturing business unit close to Dapple Corporation to produce six new designs for designer laptop covers. Operations and purchasing are not convinced this arrangement will be cost effective and so wish to conduct a breakeven analysis of the situation to ensure the designer brand manufacturer's operation is profitable. The fixed costs for rent and labour are £5,000 per month. The Forecasted Sales Price, Variable Cost and Forecasted Monthly Sales Quantity for the six new products are given in Table 3 below.

Problem 13-4 (Algo) There is a 3 percent error rate at a specific point in a production process. If an inspector is placed at this point, all the defects can be detected and eliminated. The inspector would cost $11 per hour and could inspect units in the process at the current production rate of 52 per hour. If no inspector is hired and defects are allowed to pass this point, there is a cost of $12 per defective unit to correct the defects later on. Assume that the line will operate at the same rate (i.e., the current production rate) regardless of whether the inspector is hired or not. a. If an inspector is hired, what will be the inspection cost per unit? (Round your answer to 3 decimal places.) Cost per unit b. If an inspector is not hired, what will be the defective cost per unit? (Round your answer to 3 decimal places.) Cost per unit
