Eastbay Hospital has an auxiliary generator that is used when power failures occur. The generator is worn out and must be either overhauled or replaced with a new generator. The hospital has assembled the following information:
Present Generator New Generator
Purchase cost new $ 24,000 $ 30,000
Remaining book value $ 17,000 -
Overhaul needed now $ 16,000 -
Annual cash operating costs $ 15,500 $ 10,500
Salvage value-now $ 12,000 -
Salvage value-eight years from now $ 11,000 $ 22,000
If the company keeps and overhauls its present generator, then the generator will be usable for seven more years. If a new generator is purchased, it will be used for seven years, after which it will be replaced. The new generator would be diesel-powered, resulting in a substantial reduction in annual operating costs, as shown above.
The hospital computes depreciation on a straight-line basis. All equipment purchases are evaluated using a 12% discount rate. (Ignore income taxes.)
Required:
1. Determine the net present value using the total-cost approach. (Any cash outflows should be indicated by a minus sign. Round discount factor(s) to 3 decimal places and intermediate calculations to nearest dollar amount.)
2. Using the incremental approach, determine the net present value in favor (or against) purchasing the new generator. (Round discount factor(s) to 3 decimal places.)

Imagine us is a startup that offers high definition 3d prenatal ultrasounds for high-end customers. the service process includes four activities that are conducted in the sequence described below. (the time required for each activity is shown in parentheses): activity 1: welcome a patient and explain the procedure. (20 minutes)activity 2: prep the patient (e. g., show them to the room, apply ultrasound gel). (17 minutes) (*your id number represents the amount of time needed to complete this task)activity 3: take images. (5 minutes)activity 4: discuss diagnostic with patient. (20 minutes)at each location there are employees (servers) s1, s2, and s3. the assignment of tasks to servers is the following: s1 does activities 1 and 2.s2 does activity 3.s3 does activity 4.a. what is the capacity of this process (in customers per hour)? b. suppose 3 patients arrive every hour on average. ignoring any “start of day” or “end of day” effects, what are the utilizations of all three servers (%)? c. suppose each activity can be done by any server and any server can do any set of activities. however, each activity is done by only one server. for example, a possible assignment includes: s1 does activity 1, s2 does activity 2, and s3 does activities 3 and 4. of course, the original assignment of servers to activities is also feasible. what is the maximum capacity of the process (in customers per hour)? d. now consider the capacity measures in (c) and (a), what is the percentage change? why can you improve capacity without using additional resources? (there is no free lunch, right? )note: for all hw assignments, show your process of getting the results. only providing the final answers is not acceptable and will get 0%. if necessary, use a separate sheet of paper to show your work.
