This question is a practice question not something I am submitting:

The boosters of the athletic program at a small college were trying to get uniforms and equipment for its football team. By a stroke of luck, a wealthy alumnus of the school happened to have forty football helmets. The boosters wrote and asked him to donate the helmets. The alumnus wrote back a very short letter in which he stated only that he would donate the helmets. Unfortunately, during the first day of practice in the hot sun, the helmets melted and became unusable. The boosters are demanding that the alumnus replace the helmets because he has breached an express warranty and the implied warranty of merchantability. The alumnus contends that there was no contract because there was no consideration, and thus he is liable for nothing. Evaluate each of the claims individually and state which party should prevail.
