Calculate the consumer surplus in this market? What is the market's willingness to pay

Answer 1

SOLUTION

GIVEN DATA

demand function is

Q=120-4P+0.01M

M is 40000$

so demand function is

Q=520-4P

and P=10 so

Q=520 - 40

Q=480

to see the choke price

Q=0

so

0=520 - 4P

then

P=130

there we have a triangle with height=130-10=120

and base= 480

so

consumer surplus =$\frac{1}{2}\times height\times base$

$consumer\space surpluse=\frac{1}{2}\times120\times480 =28800$
