Predict the impact on the supply and/or demand for physiotherapy services in each of the situations described below. In each case, draw a graph that includes an original supply and demand curve as well as the new, predicted supply or demand curve. Note: You are not required to submit the graphs; however, you must indicate the supply and/or demand curve shifts, the direction of each shift, and the predicted changes in equilibrium price and quantity (increase, decrease, or indeterminate).
