You have signed a contract to build a garage for the Simpsons. You will receive a$$500$ bonus for

completing the project within $17$ working days. The contract also contains a penalty clause in

which you will lose $$100$ for each day the project takes longer than working days.

Draw a project network given the following information. Complete the forward and backward

pass, compute activity slack, and identify the critical path. Do you expect to receive a bonus or a

penalty on this project?ID Description Predecessor Time
