Seatwork #3 Analyzing Market Equilibrium Questions: 1. Prove that common sense, law of diminishing marginal utility, income and substitution effect supports the inverse relationship of the Law of Demand. Use graph or illustration to defend your answer (only if applicable). (20 pts) Using P&T Accounting Services as your subject commodity, explain how the changes in the determinants of demand (taste, income, price of related goods, price expectation, and number of buyers) will affect the demand for P&T Accounting Services. (15 pts) Assume that demand for a commodity is represented by the equation P=100.2Qd and supply by the equation P=2+0.2Qs, where quantity demanded and supplied is, respectively, Qd and Qs. Using the equilibrium condition Qs = Qd, solve the equations to determine equilibrium price and equilibrium quantity. Graph the two equations to substantiate your answers if the market prices are 2, 4, 6, 8, and 10. (25 pts)
