Sebastian will buy the first three cans because his willingness to pay ($0.95, $0.80, $0.60) is greater than or equal to the price ($0.50). His consumer surplus is the sum of the differences between his willingness to pay and the price for these cans: ($0.95 - $0.50) + ($0.80 - $0.50) + ($0.60 - $0.50) = $0.45 + $0.30 + $0.10 = $0.85.
