Answer:
Betty and Steve should pay for the meal.
Step-by-step explanation:
Betty and Steve have entered into an implied contract with the restaurant.
An implied contract is legally binding. The circumstances, actions, or conduct of one or more participants in the deal sanctions the contact. In this situation, Betty and steve initiated the implied contract when they ordered and consumed the plates of pasta. In that circumstance, no written agreement is required. The act of consuming made the contract enforceable.
