A contractor must pay a penalty if work on a project is not completed on time. The penalty on the first day is $300. The penalty increases to $500 on the second day, to $700 on the third day, and so on. The contractor ended up having to pay a penalty of $4500. This is the number of days after the due date that the project was completed.
