a. On March 20, Andy Small became seventeen years old, but he appeared to be at least eighteen (the age of majority). On April 1, he moved into a rooming house in Chicago and orally agreed to pay the landlady $800 a month for room and board, payable at the end of each month.
b. On April 4, he went to Honest Hal's Carfeteria and signed a contract to buy a used car on credit with a small down payment. He made no representation as to his age, but Honest Hal represented the car to be in top condition, which it subsequently turned out not to be.
c. On April 7, Andy sold and conveyed to Adam Smith a parcel of real estate that he owned. On April 30, Andy refused to pay his landlady for his room and board for the month of April; he returned the car to Honest Hal and demanded a refund of his down payment; and he demanded that Adam Smith reconvey the land, although the purchase price, which Andy received in cash, had been spent in riotous living. Decisions as to each claim?
