Answer: excused by Delta's failure to pay.
Step-by-step explanation:
Delta Construction Corporation hires Eagle Electrical Company, as a subcontractor, to wire its new office building. After the completion of the work, Eagles is owed more than $50000.
Eagle's suspension of work is most likely due to the excuse by Delta's failure to pay. Delta has a right to pay up the money owed to Eagle. Lack of payment can lead to court cases.
