The publisher iLOVEbooks has the exclusivity on the publication of the bestseller of the year. The demand for this book isD(p)=100-p/2, and the cost of producing each book equals20.

Question 1:

Find the optimal price, the quantity produced, the monopolist's profit, and the consumer surplus.

pM=120;qM=40;M=4800;CS=1600;

pM=100;qM=50;M=5000;CS=2000;

pM=110;qM=45;M=4050;CS=2025;

All the other solutions are wrong.

Question 2:

Word has spread about the quality of the book. So much so, that when the second book of the same author is published, the readers who had read the first book(half of the total) have a higher demand function,D(p)=200-p/2, while the other half maintains the original demand function. To increase your profit, iLOVEbooks publisher sets a different price for both types of readers, whom they can identify depending on whether they bought the first part(the book was sold online, all buyers are identified ). Letp1be the prices for the second book to be change to those who did not buy the first book, and letp2be the price for those who previously bought the first book. Calculate the optimal prices.

p1=110;p2=210;

All the other solutions are wrong.

p1=110;p2=110;

p1=105;p2=205;

Question 3:

Word has spread about the quality of the book. So much so, that when the second book of the same author is published, the readers who had read the first book(half of the total) have a higher demand function,D(p)=200-p/2, while the other half maintains the original demand function. To increase your profit, iLOVEbooks publisher sets a different price for both types of readers, whom they can identify depending on whether they bought the first part(the book was sold online, all buyers are identified ). Letp1be the prices for the second book to be change to those who did not buy the first book, and letp2be the price for those who previously bought the first book.

Calculate the number of books sold and the publisher's profit.

q1=46;q2=96;M=11100

q1=45/2;q2=95/2;M=11050

All the other solutions are wrong.

q1=45;q2=95;M=11000
