Answer:
c. Julia is incorrect; she and Tumi have a valid and enforceable contract.
Step-by-step explanation:
A contract is not only enforceable through a written argument. Any word of mouth to which both the parties agree in their due consciousness, is legally enforceable.
Here, Tumi asks Julia to accept the offer of selling bags to her at $318 each. And that Julia replies with ayes to it. After receiving the bags, she cannot say that she is not interest, And there is no legal contract.
Accordingly Julia is not correct, there is a contract binding her to accept the bags and make payment.
