Final answer:
The contractor would be entitled to $415,000 in damages.
Step-by-step explanation:
To determine the amount the contractor would be entitled to in damages using the reasonable cost of completion formula, we need to subtract the amount already expended from the estimated cost of completion. The formula is:
Amount of damages = Cost of completion - Expenditure
Plugging in the values given in the question:
Amount of damages = $625,000 - $210,000 = $415,000
Therefore, the contractor would be entitled to $415,000 in damages.
