Footballs are made using a four-step process. In the stamping step, the leather is cut and stamped with the appropriate logo. This takes 15 seconds per football, and the process is staffed with six people. In the stitching step, the four panels are sewn together. This takes 25 seconds per ball, and the process is staffed with ten people. In the bladder insertion step, a rubber inflatable bladder is inserted inside the sewn panels and is partially inflated. This step takes 20 seconds per ball and is performed by eight people. The final step, lacing, is completely manual, taking 40 seconds per ball. What is the minimum number of workers to use at lacing to ensure that the overall process capacity is 1,440 footballs per hour?
