Austin and Erin are willing to pay $10 and $9, respectively, for a ticket to a screening of a new movie. What is the total consumer surplus for both Austin and Erin if the market price of a ticket is $6?

A) $4

B) $7

C) $9

D) $19

B) $7

Explanation:

The computation of the consumer surplus is shown below:

Consumer surplus = Willing to pay - Market price

For Austin, The consumer surplus = $10 - $6 = $4

For Erin, The consumer surplus = $9 - $6 = $3

So, the total consumer surplus = $4 + $3 = $7

Simply we deduct the market price from the willing to pay so that the consumer surplus can be computed
