Under the law, based on the description given, what type of performance has the contractor given?Will Brenda and the committee be required to pay the $125,000? Explain.

Brenda is an architect commissioned to design and build a new Presidential Library. The City and the fundraising and development committee have already obtained the perfect piece of land. Brenda and the committee have been working with a general contractor, and the contractor has finished most of the construction on time. Brenda included a specific type of marble to be used at the entrance, but due to shipping delays, the contractor used a similar marble. The color and quality of the marble is very close to what Brenda included in the contract. The average museum visitor would not notice unless told about the change. The museum is now finished, and the last installment of $125,000 is due. Brenda and the committee ask you whether they have to pay the contractor. 1.
