Saddler inc. makes high quality leather seats for racing bicycles and sells them to many of the top bicycle manufacturers. there are eight available sources of the type of leather that saddler uses, and all of them are located in the republic of anaerobia. saddler has always dealt with only one company in the republic of anaerobia primarily due to its reasonable cost. zappit inc. has a contract with saddler for 10,000 seats. zappit has just received a letter from saddler explaining that due to political turmoil in anaerobia its supplier cannot export the product. therefore, saddler cannot complete the contract. which of the following is most likely to be true in this scenario? a. saddler can be excused for nonperformance based on impossibility of performance. b. zappit can rightfully file a lawsuit, and saddler will be liable to pay zappit damages for nonperformance. c. saddler can be excused for nonperformance based on substantial performance. d. zappit can sue for specific performance if the seats are typical of all bicycle seats and not special or unique in any way. e. zappit can sue for material breach, and saddler cannot be excused for nonperformance.

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.
