I need help identifying an issue, decision, support, and dissent on a business law 1 case.

A person who

inherited a house is finally trying to repair it after owning it for 10 years. He agrees with a general contractor who specializes in carpentry to repair the house for $30,000. The house also had electrical and plumbing issues. The contractor offered to help fix this as well with other subcontractors. The owner agreed thinking the cost was still going to be $30,000. When the house was completed, the contractor demanded $48,000. The owner refused, and the contractor sued.
