General Foundry has been running a project to integrate a new air pollution system into their equipment. At this point, their manager, Lester Harky, would like to evaluate the progress. He is particularly interested in cost overruns or under runs for the activities, and whether the project, as a whole, is over or under budget. The relevant data is provided in the table below. What is the difference between value of the work completed for Activity A and the actual cost of Activity A? (A positive value means the actual cost exceeds the value of the work completed) What is the difference between value of the work completed for Activity B and the actual cost of Activity B? What is the difference between value of the work completed for Activity C and the actual cost of Activity C? What is the difference between value of the work completed for Activity D and the actual cost of Activity D? What is the difference between value of the work completed for Activity E and the actual cost of Activity E? What is the difference between value of the work completed for Activity F and the actual cost of Activity F? What is the difference between value of the work completed for Activity G and the actual cost of Activity G? What is the difference between value of the work completed for Activity Hand the actual cost of Activity H? Currently the total project is: over budget by $1,975; under budget by $1,97S; over budget by $4,080, or under budget by $4,080
