Ali co. bought a machine on january 1, year 1, for $24,000, at which time it had an estimated useful life of 8 years, with no residual value. straight-line depreciation is used for all of ali's depreciable assets. on january 1, year 3, the machine's estimated useful life was determined to be only 6 years from the acquisition date. accordingly, the appropriate accounting change was made in year 3. the direct effects of this change were limited to the effect on depreciation and the related provision for income tax. ali's income tax rate was 40% in all the affected years. in ali's year 3 financial statements, how much should be reported as the cumulative effect on prior years because of the change in the estimated useful life of the machine?
a) $2,700
b) $2,000
c) $1,200

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.
