Suppose that a price discriminating monopolist has segregated its market into two groups of buyers shown in the table below.

Instructions:

Enter only whole numbers. If you are entering a negative number, be sure to include a negative sign (-) in front of that number.

a) Calculate the missing total-revenue and marginal-revenue amounts for Group 1.

Group 1					Group 2
Price	Quantity Demanded	Total Revenue	Marginal Revenue		Price	Quantity Demanded	Total Revenue	Marginal Revenue
$115	0	$0			-	-	-	-
100	1	____	$____		-	-	-	-
83	2	____	____		-	-	-	-
71	3	____	____		$71	0	$0	-
63	4	____	____		63	1	63	$63
55	5	____	____		55	2	110	47
48	6	____	____		48	3	144	34
42	7	____	____		42	4	168	24
37	8	____	____		37	5	185	17
33	9	____	____		33	6	198	13
29	10	____	____		29	7	203	5

Total Revenue: $

Marginal Revenue: $

b) Assume that MC is $13 in both markets and MC = ATC at all output levels. What price will the firm charge in each market?

Group 1:

units at a price of $

Group 2:

units at a price of $

c) Based solely on these two prices, which group has the higher price elasticity of demand? ( Group 1 or Group 2 )

d) What will be the monopolist's total economic profit? $
