seven questions test.this is one of the question I will

1. suppose seven individuals enjoy going to the comedy club. Their demand is as follows.

PersonWillingness to pay 
Allison 20  
Beatrice 18 
 Cally  16  
David  14 
 Ezekiel 12 
 Francesca 10  
Gertrude  8 
Suppose the comedy club had a monopoly and a marginal cost of $7 per entrant. Suppose the club could perfectly price-discriminate. That is, it could charge each customer a different price equal to his or her maximum willingness to pay. How many tickets would the comedy club sell?

The figure below shows the market for one hour of economics tutoring at your college. Imagine that the market for economics tutoring could be perfectly competitive, controlled by a monopolist who charges a single price or a monopolist who charges each customer a different price. Use the information in the diagram to answer the questions below.

3. A diner has no competition when it comes to its famous Reuben sandwich combo plate, for which the graph shows the diner’s demand (D), marginal cost (MC), and marginal revenue (MR) curves. The price of $20 is based on the MR = MC rule for profit maximization. The rectangular region shown represents the net revenue from sales of the sandwich (total revenue from Reuben combo sales minus total variable costs associated with Reuben combo sales).

Now, suppose the diner decides to raise the price during the lunch hour, which accounts for 60% of Reuben combo sales, knowing that its lunch-hour patrons are the most loyal buyers of the Reuben combo and also that they are locked into the lunchtime slot by their work schedules. The diner raises the price just enough not to lose any lunch-hour buyers. Use the area tool to outline the region representing the resulting additional net revenue from the price increase. Your answer should be a rectangle drawn with four corners.

Part 2   (0.7 point)
See HintAs a result of the revised price structure, the diner’s net revenue from Reuben-combo sales goes from   $   to  $  per day.

4. For a firm that is a price maker for its product, the graph shows the demand (D) and marginal revenue (MR) curves, as well as the marginal cost curve (MC), which is also the average variable cost (AVC) curve.

The graph also shows the net revenue (total revenue from product sales, minus total variable costs) when the profit-maximizing rule MR = MC is applied.

Finally, the graph shows two price points the firm is considering for a price-discrimination plan. If the firm is able to carry out this plan, getting the higher price from all those willing to pay it and the lower price from those who are not, outline the region representing the resulting net revenue. Use the area tool to draw the new net revenue region on top of the old one. Your answer should be drawn with six corners.

Metropolitan Opera tickets are most expensive on Saturday night. Nevertheless, a very limited number of student rush tickets are often available, and a lucky student can wind up paying $20 for a $250 seat. The student rush tickets are available on a first-come, first-serve basis.
2nd attempt
Part 1   (0.3 point)
See HintWhy does the opera company offer these low-priced tickets?

Choose one or more:A. This creates a frenzy for last-minute student tickets.B. It wants students to have access to shows at a low price.C. It is able to sell seats that would otherwise go unsold.D. It knows that all students have an elastic demand for opera tickets. 
Part 2   (0.3 point)
See HintHow does the opera company benefit from this practice?

Choose one or more:A. The Met is able to charge different prices to different groups, raising its profits.B. The Met can increase attendance among a group of people with more elastic demand by charging them a lower price.C. The Met is able to generate revenue from unsold seats without having to drop the price for nonstudents.D. The Met can effectively price-discriminate between students and nonstudents. 
Part 3   (0.3 point)
See HintWhy are students, and not other groups of customers, offered the discounted tickets?

Choose one or more:A. In general, students have a more elastic demand.B. In general, students have a more inelastic demand.C. In general, students are more flexible and willing to buy tickets at the last minute.D. In general, students love opera.
