Abraham drinks Mountain Dew. He can buy as many cans of Mountain Dew as he wishes at a price of $0.55 per can. On a particular day, he is willing to pay $0.95 for the first can, $0.80 for the second can, $0.60 for the third can, and $0.40 for the fourth can. Assume Abraham is rational in deciding how many cans to buy. His consumer surplus is

It will purchase 3 cans

total consumer surplus 0.70

Explanation:

the market price is 0.55

It will purchase up to three cans. the fourth can he is willing to purchase at 0.40 but the price is 0.55 so it won't trade for that one.

consumer surplus:

difference between the amounts he was willing to pay for each unit and the market price:

first can 0.95 - 0.55 = 0.40

second can 0.80 - 0.55 = 0.25

third can 0.60 - 0.55 = 0.05

total consumer surplus 0.70
