Johnson purchased construction equipment from Wilson Equipment Co., Inc. for $10,500.00. However, after some of the equipment proved to be defective, Johnson sent Wilson a check for $7,000.00 marked "by endorsement this check is accepted as payment in full." Wilson endorsed and deposited the check. May Wilson force Johnson to pay the remaining $3,500.00 - why or why not? What additional facts might you need to know to come to a definitive answer?
