By studying, will can produce a higher grade, gw, on an upcoming economics exam. his production function depends on the number of hours he studies marginal analysis problems, a, and the number of hours he studies supply and demand problems, r. specifically, gw = 2.5(a)^(0.36)b^(0.64). his roommate david's grade production function is gd=2.5a^(0.25)b^(0.75).

a. what is will's marginal productivity from studying supply and demand problems? what is david's?
b. what is will's marginal rate of technical substitution (mrts) between studying the two types of problems? what is davids?
c. is it possible that will and david have different marginal productivity functions but the same marginal rate of technical substitution functions? explain.

Electronics assembly inc. is a contract manufacturer that assembles consumer electronics for a number of companies. currently, the operations manager is assessing the capacity requirements as input into a bid for a job to assemble cell phones for a major global company. the company would assemble three models of cell phones in the same assembly cell. setup time between the phones is negligible. electronics assembly inc. operates two 8-hour shifts for 275 days per year. cell phone demand forecast (phones/year) processing time (minutes/phone) mars 47,000 19.8 saturn 35,000 20.7 neptune 7,500 16.2 a. calculate total capacity required by line. b. determine the total operating time available. c. calculate the total number of assembly cells. (round up your answer to the next whole number.)

Review the wbs and gantt chart you created previously. propose three to five additional activities that would you estimate resources and durations. now, identify at least eight milestones for the recreation and wellness intranet project. remember that milestones normally have no duration, so you must have tasks that will lead to completing the milestone. add your activities and milestones to your gantt chart, creating a new gantt chart. estimate the task durations and enter dependencies as appropriate. remember that your schedule goal for the project is six months. copy the gantt chart and network diagram to a word document.
