Answer:
- Yes,
- Bilateral, Implied contract which is enforceable.
Step-by-step explanation:
Note, both parties consented to a contract even though it was an informal setting. Remember, certain gestures were used by Ed to show contract acceptance, There's also valid consideration since the value of the exchange is known; which is a candy bar for $1.
Fran thus understands that Ed will pay for the candy later since he saw the sign, this also makes it a bilateral contract (between two parties only). The contract is also enforceable since it is legal to sell candies.
