Ritz products's materials manager, tej dhakar, must determine whether to make or buy a new semiconductor for the wrist tv that the firm is about to produce. four million units are expected to be produced over the life cycle. if the product is made, start-up and production costs of the make decision total $3 million, with a probability of 0.3 that the product will be satisfactory and a 0.7 probability that it will not. if the product is not satisfactory, the firm will have to reevaluate the decision. if the decision is reevaluated, the choice will be whether to spend another $3 million to redesign the semiconductor or to purchase. likelihood of success the second time that the make decision is made is 0.8. if the second make decision also fails, the firm must purchase. regardless of when the purchase takes place, dhakar's best judgment of cost is that ritz will pay $0.40 for each purchased semiconductor plus $1 million in vendor development cost.

Who is better at multi-tasking? in business, employees are often asked to perform a complex task when their atten-tion is divided (i. e., multi-tasking). human factors (may 2014) published a study designed to determine whether video game players are better than non–video game play-ers at multi-tasking. each in a sample of 60 college stu-dents was classified as a video game player or a non-player. participants entered a street crossing simulator and were asked to cross a busy street at an unsigned intersec-tion. the simulator was designed to have cars traveling at various high rates of speed in both directions. during the crossing, the students also performed a memory task as a distraction. two variables were measured for each student: (1) a street crossing performance score (measured out of 100 points) and (2) a memory task score (measured out of 20 points). the researchers found no differences in either the street crossing performance or memory task score of video game players and non-gamers. “these results,” say the researchers, “suggest that action video game players [and non-gamers] are equally susceptible to the costs of dividing attention in a complex task”

Kenney co. uses process costing to account for the production of canned energy drinks. direct materials are added at the beginning of the process and conversion costs are incurred uniformly throughout the process. equivalent units have been calculated to be 19,200 units for materials and 16,000 units for conversion costs. beginning inventory consisted of $11,200 in materials and $6,400 in conversion costs. april costs were $57,600 for materials and $64,000 for conversion costs. ending inventory still in process was 6,400 units (100% complete for materials, 50% for conversion). the total cost per unit using the weighted average method would be closest to:
