Terrance, a golf greens architect, agrees with Artis to direct a current construction project for $9,000. During the course of the project, Terrance, for no apparent reason, takes away the plans for the project and refuses to continue working unless Artis promises to pay him an extra $3,000. Artis agrees. If Terrance resumes work following Artis promise to pay additional funds, has a contract for an additional $3,000 formed? Explain
