Mr. X enters into a contract with Mr. Z under which Z agreed to build a customized telescope for X for $500. The value of the completed telescope to X will be $600. Expecting that the telescope will be delivered on schedule, X pays the purchase price to Z and drills a hole in his roof at a cost of $300. However, before Z delivers the telescope, Ms. Y, another amateur astronomer, offers to buy it from Z for $550. Would Z breach his contract with Mr. X if the measure of damages were (1) the expectation interest (2) the restitution measure (3) the reliance measure? Explain why in detail.
