Forrest Gump drinks Dr. Pepper. He can buy as many cans of Dr. Pepper as he wishes at a price of $0.50 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 that Forrest is rational in deciding how many cans to buy. His consumer surplus will be, O $0.50 O $0.85 O $1.05 O $1.20
