Angelo recently completed his residency in internal medicine and has decided to open his own practice. In interviewing potential office assistants, Angelo discovered that the best candidate types 25 words per minute. Thanks to an excellent typing course in high school and lots of practice writing for his college newspaper, Angelo can type 50 words per minute himself. Assume the current wage for office assistants is $10 per hour and that doctors can see four patients per hour. Also assume the office assistant has neither the knowledge nor the license necessary to treat patients.
3.3. What price (in dollars per patient visit) would make Angelo indifferent between hiring an office assistant and doing the typing himself?
