A city engineer must choose between two different routes for a new sewerline. Route 1 is a 20,000-foot gravity line, which includes 8000 feet of tunnelingat $250 per foot. The remaining 12,000 feet will cost $80 per foot. The annualmaintenance cost is expected to be $2000. Route 2 is a 23,000-foot linerequiring a pumping station, which will cost $840K to build and $15K annuallyto operate and maintain. The sewer line costs $80 per foot and will cost $2100annually to maintain. The expected life of the station and both lines is 35years. Using an interest rate of 8%, which route should be chosen using:a. RORAIb. AWC

Quorex is evaluating two mutually exclusive projects. Project A has a net investment of $50,000 and net cash flows over a six-year period of $13,000 per year (NOTE: that project requires a reinvestment with the same cost and cash flow for another six years). Project B has a net investment of $48,500, but its net cash flows of $8,740 per year will occur over a 12-year period. If Quorex has a cost of capital of 14% for these projects, which project, if either, should be chosen, and what is its NPV?

The Sam & Irene Black School of Business at Penn State Erie, The Behrend College, has the facilities and faculty to accommodate an enrollment of 1,500 new students per academic year. Yet, to maintain small class sizes (less than 45), the school's chancellor, Ralph Ford, placed a ceiling of 1,300 on the enrollment of new students.

What is the capacity utilization for this system? Between 60% to 70% Lower than 60% Between 70% to 80% Higher than 90% Between 80% to 90%
Three graduates who recently graduated from the College of Law are considering opening a law office in that would make inexpensive legal services available to those who could not afford these services elsewhere. The intent is to provide easy access for their clients by having the office open 300 days a year, 8 hours each day from 8 A.M. to 4 P.M. The office will be staffed by a lawyer, assistant, secretary, and receptionist. To assist with market projections and to determine the feasibility of this project, the three graduates hired a management accountant who graduated from the College of Business and Economics of 8 years ago. The results of this market study show that if the firm spends USD 500,000 on advertising in the first year, the number of new clients expected each day may have the following probability distribution: Number of new clients per day Probability Expected Outcome 20 0.1 2 30…
