Answer:
Total consumer surplus is $12
Step-by-step explanation:
Consumer surplus can be defined as the difference between what the consumer is willing to pay for a particular product and its market price.
Given:
Market price of product is $5
Consumer's willingness to pay for 1st unit = $12
Consumer surplus of first customer = 12-5 = $7
Consumer's willingness to pay for 2nd unit = $8
Consumer surplus of second customer = 8-5 = $3
Consumer's willingness to pay for 3rd unit = $7
Consumer surplus of first customer = 7-5 = $2
Total consumer surplus = 7+3+2
= $12
