Challenging economic conditions in several countries have pushed freight shipping companies to look for additional sources of revenue in addition to the revenue generated by hauling freight across the ocean. in recent years, one additional source of revenue for these freight companies has been to take on cruise passengers in addition to regular cargo. generally, there are only 2 – 12 passengers on a cargo ship. demand for cargo ship cruises is high; travelers need to book months in advance. typically, passengers taking a cruise on a cargo (or container) ship will get an air-conditioned room with private bathroom for about $115 per day. meals are included; passengers will share three meals a day with the crew. the rooms are cleaned once a week by the ship’s steward. passengers have to wash their own clothes. entertainment options include walking or running on deck, playing ping pong or darts, watching or listening to cds/dvds, and swimming in the on-ship pool if available on that particular ship. passengers can disembark at various ports for sightseeing. typically, a ship makes a 12 – 24 hour stop at each port on its itinerary for the loading and unloading of freight.
international regulations dictate that ships carrying more than twelve passengers have an on-board physician and a small hospital or treatment center. (crew members, of which there are usually 15 – 25 per freighter, are not considered passengers.)
what costs might be variable with respect to passengers carried on a cargo ship?
a. pool depreciation, salary of the crew members, cost of meals.
b. cargo fuel, salary of the captain, salary of the crew members
c. cost of meals, cost of toiletries, ping pong balls
d. salary of the physician, salary of the crew members, cost of meals

Anew 2-lane road is needed in a part of town that is growing. at some point the road will need 4 lanes to handle the anticipated traffic. if the city's optimistic estimate of growth is used, the expansion will be needed in 4 years and has a probability of happening of 40%. for the most likely and pessimistic estimates, the expansion will be needed in 8 and 15 years respectively. the probability of the pessimistic estimate happening is 20%. the expansion will cost $ 4.2 million and the interest rate is 8%. what is the expected pw the expansion will cost?

Why entrepreneurs start businesses. a) monopolistic competition b) perfect competition c) sole proprietorship d) profit motive

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.
