A roofer is working to cover a 2,500-square-foot roof. He must first install rafters, then sheathing, then felt, and finally shingles. He assumes the previous tasks com- pose 35%,20%,15%, and 30% of the total roofing activity, respectively. At a certain point, the roofer gets the following information on the subtasks: Subtask Unit1 Total Quantity Installed Quantity Rafters EA 150 102 Sheathing SF 2,720 1,200 Felt SQ 27.2 10 Shingles SQ 27.2 5 1EA=each; SF=square feet. SQ (square), is 100 square feet; a unit used mostly in roofing jobs. Calculate the estimated percent complete for the roofing activity
