A. Boba, who was unemployed, registered with the Slow Employment Agency. A contract was then made under which Boba, in consideration of such position as the agency would obtain for her, agreed to pay the agency one half of her first month's salary. The contract also contained an assignment by Boba to the agency of one half of her first month's salary. Two weeks later, the agency obtained a permanent position for Boba with the Alkret Co. at a monthly salary of $1, 900. The agency also notified Alkret Co. of the assignment by Boba. At the end of the first month, Alkret Co. paid Boba her salary in full. Boba then quit and disappeared. The agency now sues Alkret Co. for $950 under the assignment. Who will prevail and why? Please be specific! B. On November 23, Sylvia agreed to sell to Boba her Pontiac automobile for $7,000, delivery and payment to be made on December 1. On November 26, Boba informed Sylvia that she wished to rescind the contract and would pay Sylvia $350 if Sylvia agreed. She agreed and took the $350 cash. On December 1, Boba tendered to Sylvia $6,650 and demanded that she deliver the automobile. Sylvia refused and Boba initiated a lawsuit. May Boba enforce the original contract? Please be specific!
