Follow me, Mortal, and I shall lead you through the treacherous waters of the formula of the Learned Restatement.

First, we must determine the "loss in value" suffered by the Non-Breaching Doofisious. (The contract price was 9,000 drachmas. Odysseus paid Doofisius 2,000 drachmas. If the contract had been performed, it would have cost Doofisius 7,000 to perform. Three thousand drachmas were spent prior to breach.)

What is the "loss in value," mortal? (Remember, that is "the loss in the value to him of the other party's performance caused by its failure or deficiency." In other words, it's the amount that the non-breaching party would have received but didn't.)
