4. Rene is working with the operations manager to determine what the standard labor cost is for a spice chest. He has watched the process from start to finish and taken detailed notes on what each employee does. The first employee selects and mills the wood, so it is smooth on all four sides. This takes the employee 4 hour(s) for each chest. The next employee takes the wood and cuts it to the proper size. This takes 7 minutes. The next employee assembles and sands the chest. Assembly takes 4 hour(s). The chest then goes to the finishing department. It takes 3 hour(s) to finish the chest. All employees are cross-trained so they are all paid the same amount per hour, $19.77.

What is the standard cost per chest for labor? Round to the nearest penny, two decimal places.
