Demand for the popular water toy Sudsy Soaker has far exceeded expectations. In order to increase the availability of different models of the toy, the manufacturer has decided to begin producing its most popular models as often as possible on its one assembly line. Given monthly requirements of 7200, 3600, and 3600 units for Sudsy Soaker 50, Sudsy Soaker 100, and Sudsy Soaker 200, respectively determine a model sequence for the final assembly line that will smooth out the production of each model. (Assume 30 working days per month and eight working hours per day. Also assume that the time required to assemble each model is approximately the same.)
