A hospital is considering a new procedure to be offered at $200 per patient. The cost involved per year are: patient meal $10, electricity bill for operating air-conditions in theatre room $25, surgical equipment $52,000 consultation fee for doctor $20, ambulance $30,000, cleaning bedsheet for patient $10, salary of ambulance driver $1000, capital for medicine $15,000, taxes and municipal levy $2,000, and patient admission fee $35. What is the break-even quantity for this service? If the most pessimistic sales forecast a for the proposed service were 1,500 patients, what would be the procedure's total contribution to profit and overhead per year?
