Having issues with some of this .. Any assistance would be greatly appreciated!

10. List and very briefly explain the three types of barriers to entry that can cause a monopoly situation to arise. 11. Draw a demand and supply curve. Label the axes, P*, Q*, consumer surplus, and producer surplus.12. Solve for Co in the two-period consumption model with the following given information: Y1 = 500 Y2 = 700 r = 6%% C1 = 450 13. Solve for Ya in the two-period consumption model with the following given information: . Y1 = 1,100 . T = 3% C1 = 1,250 C2 = 1,40014. A monopolist has the following cost and revenue information. Complete the table and use it to answer the questions that follow. Costs Revenues Quantity Total Marginal Quantity Price Total Marginal Produced Cost (S) Cost Demanded (S/unit) Revenue Revenue 100 n/ 170 n/a 140 160 2 184 2 150 230 3 140 4 280 130 335 120 395 6 110 7 475 7 100 565 90 15. What are the firm's fixed costs? 16. What is 0*? 17. Given 0*, what is P*? 18. How much profit does this monopolist make?19. Discriminating monopolists are able to charge different prices to different customers. In fact, a perfectly discriminating monopolist is able to charge each customer his exact (personal) reservation price for the item the monopolist sells. Explain why this would be 7 beneficial for the monopolist in terms of his revenue and profit. A graph might help you. (Think about what this would mean for the monopolist's MR curve as you answer this question. Look back at the notes where we discussed the costs and benefits for a monopolist to raising price. What happens to the cost if he is perfectly discriminating?)\f4. Complete the table below for a monopolist concerning his costs. Round to two decimal ElEIEE'S for an? noninteger answers. 5. Given the information in your tables for problems #3 and 4, how much does the monopolist produce? 6. Given your answers to problems #3-5, how much revenue does the monopolist receive? 7. Given your answers to problems #3-5, what are the total costs that the monopolist has? 8. Given your answers to problems #6 and 7, what is the monopolist's profit? 9. Why would an increase in the demand curve benefit a monopolist
