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. Superimpose the total revenue curve on top of the total cost curve in (1).
