Refer to the Figures Above

Refer to the figures above.Suppose the graphs represent the demand for use of a local golf course for which there is no significant competition (it has a local monopoly) .P denotes the price of a round of golf and Q is the quantity of rounds sold each day.If the left graph represents the demand during weekdays and the right graph the weekend demand,this profit-maximizing golf course should:

A) charge $9 for each round,regardless of the day of the week.
B) charge $7 for each round,regardless of the day of the week.
C) charge $7 for each round on weekdays,and $10 during the weekend.
D) charge $9 for each round on weekdays,and $10 during the weekend.
The monopolist should set MC = MR in both markets.That means the weekday output should be 200 per day with a price of $7 and the weekend output should be 100 per day with a price of $10.
