Your grandfather has promised to give you $500 a year at the end of each of the next four years if you earn Cs or better in all of your courses each year. Using a discount rate of 7%, which of the following is correct for determining the present value of the gift?
a. PV = $500x7%x4
b. PV = $500x(PV factor, i=4%, n =7)
c. PV = $500x(Annuity PV factor, i=7%, n=4)
d. PV = $500x(Annuity PV factor, i=7%, n=4)

Morgana company identifies three activities in its manufacturing process: machine setups, machining, and inspections. estimated annual overhead cost for each activity is $168,000, $315,900, an $97,200, respectively. the cost driver for each activity and the expected annual usage are number of setups 2,100, machine hours 24,300, and number of inspections 1,800. compute the overhead rate for each activity. machine setups $ per setup machining $ per machine hour inspections $ per inspection

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.
