Eighteen is the applicable statutory age of majority, and on that date Ohm was to receive the proceeds of a trust. On July 1, when the reasonable value of the television set was $250, Ohm sent Stereo a signed letter stating, "I'll only pay you $300; that is all the set is worth." In an action against Ohm for money damages on July 2, what is the maximum amount that Stereo will be entitled to recover?
Nothing $250, the reasonable value of the set  $300, the amount Ohm promised to pay in his letter of July 1  $400, the original sale price
