If Zuma sues Hydro-King for restitution of the $4,000 advance payment, which of the following should the court decide?
Zuma's claim should be upheld in the amount of $4,000 minus the amount of Hydro-King's lost profit under its contract with Zuma. 
Zuma's claims should be upheld in the amount of $3,500 ($4,000 minus $500 as statutory damages under the UCC)
Zuma's claim should be denied, because, as the party in default, he is deemed to have lost any right to restitution of a benefit conferred on Hydro-King. 
Zuma's claim should be denied, because, but for his repudiation, Hydro-King would have made a profit on two boat sales instead of one.
