Read Case Problem $21$ at the end of Chapter $10.$ Predict how a court will resolve the issue of Mutual Assent. In the Case Problem, you are told that the last communication from the Giannettis "changed the mortgage amount from $$124,000$ to $$128,000."$ From this, you can infer that the first communication, the one that offered $$155,000,$ included a condition that the Giannettis be approved for a mortgage loan of at least $$124,000.$ Use the facts to explain if these parties' communications satisfy the essential element of Mutual Assent. Then, assume all essential elements of a contract have been met. You may also assume that the agreement is in writing. Use the facts of Case Problem $21$ to explain whether this is a bilateral or a unilateral contract. Finally, use the facts of Case Problem $21$ to explain whether it is an executed or an executory contract.
