Final answer:
Yes, there was consideration for Abby's promise to pay DiNozzo $300.
Step-by-step explanation:
Under the law of contract, consideration is a necessary element for a promise to be enforceable. Consideration is the exchange of something valuable between parties to a contract. In this situation, DiNozzo helped Abby move into her new home, and Abby promised to pay him $300 for his services.
This promise to pay can be considered as consideration, as it is a bargained-for exchange between DiNozzo and Abby. Therefore, there was consideration for Abby's promise to pay DiNozzo $300.
