Answer:
1- The UCC contract formation includes offer, acceptance and consideration.
Explanation:
Elements "Offer" and "Acceptance" together form mutual assent. Also, in order to be enforceable, the contract must be for a legal purpose and parties to the contract must have capacity to enter into the contract, that part is related to consideration.
Offer → gives power of acceptance to another party, besides it includes the agreement´s essential elements (they have to be definite and certain).
Acceptance → must be a mirror image of the offer.
Consideration → All common-law contract must contain this element as a valid one. It means that there must be a bargained for interexchange of acts or promises, both parties incurring new legal detriment or obligations as a consequence of the contract.
