The given information cannot achieve the outcome of marginal revenue is equal to the marginal cost. However, the profit still can be maximized when marginal revenue is larger to profit is maximized when Peter serves 6 members and the price charged by him is \$300. 6. B It is asked whether the profit can be increased if peter set two different prices to two groups which are adults and children group. If yes, what are the prices?

Peter can set an optimum price to each group which is the prize they expected. Then the profit will rise. The price for adult will remain at \$300 with same explanation to 6. 2(a). The table below shows the situation on children group.

Figure 1. 1 Figure 1. Shows that a monopoly is obtaining a positive profit. The blue area is the economic profit. Figure 1. 2 shows when the average total cost increases and Just touch the marginal benefit curve. Average total cost is equal to the average revenue. So the economic profit is zero. Figure 1. Figure 1. 3 shows when the demand decreases, the marginal benefit is equal to average total cost. So the economic profit is zero again. The statement is false because when TACT increases or demand decreases, the monopoly economic profit will be zero or even negative. 6.
