Final answer:
Nick created an implied contract when he consumed Oreos and beers from the store, indicating his intention to pay for them at checkout even without an explicit agreement.
Step-by-step explanation:
When Nick signs the charge ticket at James Food Center, he has made an implied contract. Although there was no explicit discussion or agreement before the items were consumed, an implied contract is created when a person selects goods in a store and benefits from them, under the assumption they will pay for the items. This is understood through the customer's actions rather than a verbal or written agreement. Nick's consumption of the Oreos and beers demonstrates his acceptance of the goods provided by the store, with the expectation of payment upon checkout.
