2. General Equilibrium. The market demand function for the number of family doctors practicing in the Philadelphia area, OF , is OF = 250000 - SF 3 where SF represents the annual salary of Philadelphia-area family doctors. The market demand function for the number of dentists practicing in the Philadelphia area, Or, is OT = 150000 - ST 4 where S, represents the annual salary of Philadelphia-area dentists. The market supply of family doctors is OF 10 The market supply of dentists is 3 QT =- 2 -ST 10a. What is the equilibrium number of family doctors and dentists practicing in the Philadelphia area?
