"Blast it!" said David Wilson, president of Teledex Company. "We've just lost the bid oh the Koopers job by $3,000, It seems we're either too high to get the job or too low to make any money on half the jobs we bid." Teledex Company manufactures products to customers' specifications and uses a jot-order costing system. The company uses a plantwide predetermined overhead rate based on direct labor cost to apply its manufacturing overhead (assumed to be all fixed) to jobs. The following estimates were made at the beginning of the year: Jobs require varying amounts of work in the three departments. The Koopers job, for example, would have required manufacturing costs in the three departments as follows: Using the company's plantwide approach, compute the plant wide predetermined rate for the current year. Using the company's plantwide approach, determine the amount of manufacturing overiead cost that would have been applied to the Koopers job. Suppose that instead of using a plantwide predetermined overhead rate, the company hed used departmental predetermined overhead rates based on direct labor cost. Compute the predetermined overhead rate for each department for the current year. Suppose that instead of using a plantwide predetermined overhead rate, the company hpd used departmental predetermined overhead rates based on direct labor cost. Determine the amount of manufacturing overfiead cost that would have been applied to the Koopers job. Assume that it is customary in the industry to bid jobs at 150% of total manufacturing cost (direct materials, direct labor, and applied overhead). What was the company's bid price on the Koopers job using a piantw de predetermined overheod rate? Assume that it is customary in the industry to bid jobs at 150% of total manufacturing cost (direct materials, direct labor, and applied overhead). What would the bid price have been if departmental predetermined overhead rates had been used to appiy overhead cost
