Answer:
$16
Explanation:
Consumer surplus can be defined as the difference between the reservation price of a consumer for a commodity and the price he actually paid to the commodity. Reservation price is the consumer is willing to pay.
Market consumer surplus is the summation of consumer surpluses of all the consumers of a commodity.
Given the information in the question, the consumer surplus and market consumer surplus can be calculated as follows:
Jess’ consumer surplus = 0. This is because Jess will not subscribe because her reservation price $10 is less than the offer price of $12. Therefore, Jess’ consumer surplus for the magazine is zero.
Ania’s consumer surplus = $16 - $12 = $4
Mandy’s consumer surplus = $24 - $12 = $12
Chloe’s consumer surplus = $12 - $12 = $0
Market consumer surplus = $0 + $4 + $12 + $0 = $16
Therefore, the value of market consumer surplus is $16.
