On January 1, Awl and Howser agreed in writing that Awl would build a house on Howser's lot according to Howser's plans and specifications for $60,000, the work to commence on April 1. Howser agreed to make an initial payment of $10,000 on April 1, and to pay the balance upon completion of the work. On February 1, Awl notified Howser that he (Awl) would lose money on the job at that price, and would not proceed with the work unless Howser would agree to increase the price to $90,000. Howser thereupon, without notifying Awl, agreed in writing with Gutter for Gutter, commencing April 1, to build the house for $75,000, which was the fair market cost of the work to be done. On April 1, both Awl and Gutter showed up at the building site to begin work, Awl telling Howser that he had decided to "take the loss" and would build the house for $60,000 as originally agreed. Howser dismissed Awl and allowed Gutter to begin work on the house."For this question only, assume that Awl is liable to Howser for breach of contract and also assume the following additional facts: Gutter finished the house on schedule and then showed Howser that he (Gutter) had spent $85,000 on the job. Howser thereupon paid Gutter the full balance of their contract price plus an additional $10,000 so that Gutter would not lose money. In a contract action by Howser against Awl, Howser will recover
the difference between the fair market value of the completed house and Awl's original contract price. $30,000, the difference between Awl's original contract price and the amount Awl demanded on February 1.  $25,000, the difference between Awl's original contract price and the total amount Howser paid Gutter for building the house.  $15,000, the difference between Awl's original contract price and Gutter's contract price.
