Ralph is a properly licensed general contractor, and he agrees to build Jennys house for $25,000 in three years. However, six months after the work began, Ralph demands an additional $5,000 from Jenny to complete the work for no reason other than being offered a better construction job down the street that will pay more to him. Jenny agrees to pay Ralph the extra $5,000.00 to keep him working on her house. However, when the work was completed, Jenny pays Ralph only the original agreed-upon price of $25,000. Ralph decides to sue Jenny to collect the extra $5,000.00 that Jenny agreed to pay him to keep him at the job site and continue the contract. Do not address the statute of frauds (ie. assume the parties contract does not violate the statute of frauds), but answer this question--- is Ralph entitled to the extra $5,000.00 from Jenny, who did agree to pay him this extra money? Why or why not and explain what element of the contract is at issue here and why.
