{ ["Opportunity cost.", "Incentives.", "Marginal benefit and marginal cost.", "Consumer and producer surplus."]}

Adam Sandler was willing to pay { ["$0", "$50", "$200", "$300", "$500", "$600"]} for the girl's service.

The girl was willing to do it for {["$0", "$50", "$200", "$300", "$500", "$600"]}.

After the negotiation was complete, the agreed upon price was { ["$0", "$50", "$200", "$300", "$500", "$600"]},

Adam Sandler's { ["opportunity cost", "marginal benefit", "consumer surplus", "producer surplus"]} was { ["$0", "$50", "$200", "$300", "$500", "$600"]}, the girl's { ["opportunity cost", "marginal benefit", "consumer surplus", "producer surplus"]} is { ["$0", "$50", "$200", "$300", "$500", "$600"]}, and their combined {["cost", "benefit", "surplus"]} is {["$0", "$50", "$200", "$300", "$500", "$600"]}, which is equal to {["Adam Sandler's willingness to pay - the girl's cost", "The girl's cost - Adam Sandler's willingness to pay", "Adam Sandler's willingness to pay + the girl's cost", "Adam Sandler's willingness to pay / the girl's cost", "Adam Sandler's willingness to pay x the girl's cost"]}.
