Answer:
In that case, Patricia:
is still liable to pay the additional 10%.
Step-by-step explanation:
The 10% price increase was preceded by an agreement between the two parties. Patricia is bound to honor her agreements with her business partner to sustain the business relationship. Refusing to pay a debt just by a change of mind does not repudiate the contract. Nancy can enforce the agreement in the court for specific performance of the contract because this additional agreement simply modifies the earlier contract and remains enforceable.
