Jamie is building a house on her lot. She invites Earnie of Earnie's Excavation to bid on the excavation job. Earnie observes that the lot next to Jamie's is also under excavation and the soil in that lot is normal and not excessively rocky. Based on the assumption that the soil in Jamie's lot will be similar, he and Jamie agree that the excavation will cost $3,000 . When Earnie starts digging,
he learns there is solid rock under Jamie's lot. Earnie says it will cost an extra $2,500 for the excavation work. Jamie agrees just to get the job done but later refuses to pay a dime more than $3,000 . If Earnie sues, the most likely result would be: a. Jamie wins, as Earnie was under a preexisting duty to dig the basement. b. Earnie wins as this modification is governed by the UCC and consideration is not required to enforce a modification of the agreement. c. Jamie wins as Earnie was not acting in good faith and just wanted to put Jamie in a situation where she didn't have a choice but to agree to more money. d. Earnie wins, as the modification was due to unforeseen difficulties.
