The Clothing Shack is an online retailer of men's, women's, and children's clothing. The company has
been in business for four years and makes a modest profit from its online sales. However, in an effort
to compete successfully against online retailing heavyweights, the Clothing Shack's marketing
director, Makaya O'Neil, has determined that the Clothing Shack's marketing information systems
need improvement.
Ms. O'Neil feels that the Clothing Shack should begin sending out catalogs to its customers, keep
better track of its customer's buying habits, perform target marketing, and provide a more
personalized shopping experience for its customers. Several months ago, Ms. O'Neil submitted a
systems service request (SSR) to the Clothing Shack's steering committee. The committee
unanimously approved this project. You were assigned to the project at that time and have since

- Each machine costs $3 Million. Building the room with all its attendant safety protection and other ancillary costs increases the spending by an additional $2.0 million dollars per MRI suite. Each machine can perform 2000 scans per year. Each reading of an MRI scan by a radiologist, along with other per-scan-related costs, is $500 per scan. The machine will last five years. Don’t worry about discount rates for this problem Graph the total costs over 5 years as a function of sales for 0-3000 patients annually. Hint: you may need to add a second MRI at some point. Suppose that you want to make a profit of $500 per scan at a target volume of 1000 patients per year, and you purchase only one machine.
