Price indexes can be used to compare prices across different periods. Suppose that a year of tuition for college at public institutions averaged a cost of â$ in 1989 and that the CPI index was in 1989. If the CPI index was inâ 2009, then the cost of tuition inâ 2009, as the result ofâ inflation, would equal â$ . â(Enter your response rounded to the nearest wholeâ number.) Suppose that the actual average cost of tuition in 2009 was â$. Relative to the expected cost computedâ above, the cost of tuition increased by the same as less than the amount of inflation.

Because this market is a monopolistically competitive market, you can tell that it is in long-run equilibrium by the fact thatmr=mc at the optimal quantity for each firm. furthermore, a monopolistically competitive firm's average total cost in long-run equilibrium isless than the minimum average total cost. true or false: this indicates that there is a markup on marginal cost in the market for engines. true false monopolistic competition may also be socially inefficient because there are too many or too few firms in the market. the presence of the externality implies that there is too little entry of new firms in the market.
