If the monopolist faces the demand curve given by P=10-2Q, what is the quantity intercept value?

A)5

B)20

C)10

D)15

Suppose a monopolist faces two groups of consumers. Group 1 has a demand given by P₁=50-2Q₁and MR₁=50-4Q₁. Group 2 has a demand given by P₂=40-Q₂and MR₂=40-2Q₂. The monopolist faces MC=AVC=ATC=$10 regardless of which group he supplies to. We can infer from the demand equations that Group ___ is the inelastic group because the demand is ____ than that of the other group.

A)1; flatter

B)1; steeper

C)2; steeper

D)2; flatter
