Contractor & Owner sign a written contract whereby Contractor will build house for Owner for $$500,000.$

Contractor reasonably expects to make $$100,000$ profit on the work $($and can prove$/$demonstrate this$).$

The contract DOES NOT mention the possibility that the price of materials may go up or down after the contract was signed.

Additional facts for this question: After construction on the house is finished $($of high quality, & without defects$)$ & before paying any money to Contractor, Owner repudiates the contract & refuses to pay any money to Contractor. Because the cost of materials went up$/$increased during the construction, the Contractor has already spent $$550,000($five$-$hundred and fifty thousand$)$ for labor & materials to build the house. Owner refuses to pay and has not yet paid any money to Contractor.

How much $($be specific$)$ will court order Owner to pay Contractor & why?
