PB 1.

LO 8.1Sameerah is trying to determine the standard hours to make one unit. She has studied the manufacturing process and is trying to determine what portion of the employees’ time should be included in the standard time to make the product. She knows that the actual time the worker is assembling, cutting, and painting should be part of the standard hours. She is questioning whether setup, down time, rest periods, and cleanup should be part of the standard hours. Explain why you would or would not include these times.

LO 8.1Freidrich is working with the operations manager to determine what the standard material cost is for a spice chest. He has watched the process from start to finish and taken detailed notes on what material is used. The easiest material to measure is the wood. Each chest uses 5 board feet and produces 1.5 feet of scrap. He is not sure what to do with the scrap that is produced; the company cannot buy the boards in any other dimensions. What amount of materials should be included in the standard for material costs?

Compute the direct materials price variance and the direct materials quantity variance for each job and in total. Why would you want to calculate the direct materials quantity variance for each job?

During September, Corolla purchased and used 4,200 pounds of steel to make 1,040 units. They paid $20.75 per pound for the steel. Compute the direct materials price variance, the direct materials quantity variance, and the total direct materials cost variance for the month of September. What would change if Corolla had made 2,200 units?
