You run a custom t$-$shirt shop. You have a very specific process to make your t$-$shirts. First, you need to bleach the t$-$shirt, which takes $30$ seconds. Then you add colors $($done in any order$)$ that take $10$ seconds for red, $20$ seconds for blue, and $15$ seconds for yellow. After you finish all the coloring, you need to iron the shirt taking $100$ seconds, and then finally fold the shirt taking $45$ seconds. If you run your business $12$ hours a day, and you want to make $360$ shirts in a day, what is the efficiency of your optimal facility layout?
