question
Larry's Auto Body Repair Shop had revenues that averaged $60,000 per week in April and $50,000 per week in May. During both months, the shop employed six full-time (40 hours/week) workers. In April the firm also had four part-time workers working 25 hours per week, but in May there were only two part-time workers and they only worked 10 hours per week. What is the percentage change in labor productivity from April to May for Larry's Auto Body Repair?
answer
8.95% Labor productivity is output (revenue) divided by hours of labor input. For April, revenue was $60,000 and labor hours were 4 x [(40 x 6) + (25 x 4)]. This is 60,000/1,360 or 44.12 dollars per hour of labor. For May, revenue was $50,000 and labor hours were 4 x [(40 x 6) + (10 x 2)] This is 50,000/1,040 or 48.07 dollars per hour of labor a difference of $3.95 per hour. The percentage change in productivity between April and May, then, is 3.95/44.12 = 0.0895 x 100 = 8.95%. (Note: this analysis assumes four weeks in each month and equal productivity for each hour worked.)

question
at a decisions point in a decision tree, which machine would you select when trying to maximize payoff when the anticipated benefit of selecting machine A is $45,000 with a probability of 90%; the expected benefit of selecting machine B is $80,000 with a probability of 50%; and the expected benefit of selecting machine C is $60,000 with a probability of 75%?
answer
machine c EMV of machine A=0.9x45,000=40,500 EMV of machine B= 0.5x80,000=40,000; and EMV of machine C=0.75x60,000=45,000. Since $45,000>$40,500>$40,000, you would select machine C.

question
assume a fixed costs for a process of $15,000. The variable cost to produce each unit of product is $10, and the selling price for the finished product is $25. What number of units has to be produces and sold to break even?
answer
1,000 units ($25-$10=$15; $15,000/$15=1,000 units)
question
assume a fixed cost for a process of $120,000. The variable cost to produce each unit of product is $35, and the selling price for the finished product is $50. what number of units has to be produced and sold to break even?
answer
8,000 units ($50-$35=$15; $120,000/$15=8,000 units.
question
you are hired as a consultant to decide if your client should purchase a new, highly specialized piece of equipment. The product to be produced by this equipment is forecast to have a total worldwide demand of 15,000 units over the entire product life. The initial investment to acquire and install the equipment is $256,000. The variable cost to produce each unit will be $15, and the selling price for the finished product will be $30. What best describes the situation the firm is facing?
answer
the company's total margin will be less than its investment margin per unit= $30-$15=$15; $15 x 15,000 units= $225,000. Because $225,000<$256,000, the total projected margin for this product will be less than the investment required.
question
In a work center, machine A has a 10-minute set-up time per batch and a 2-minute per unit run time. Machine B performs the identical function but has a set-up time of 30 minutes and a 1-minute run time per unit. The work center makes products in batches ranging from 1 unit to 100 units. Assuming capacity is not a limitation on either machine, in order to minimize the total processing time, on which batches should machine B be used?
answer
batches of more than 20 units should be run on machine B. Total processing time for a batch of size Q: In Machine A: 10 + 2Q. In Machine B: 30 + 1Q. Point of indifference is where 10 + 2Q = 30 + Q or Q = 20. That is, for batches of size less than 20, total processing time is smaller in Machine A and for batches of size greater than 20, total processing time is smaller in Machine B. Thus, B is the most correct answer.
