In the first cost analysis of Purchase Department Cost Vs Merchandise Purchased the new model stated, y = 0.0014x + 1032703, R² = 0.0093. The second model of Purchase Department Cost Vs Number of Purchase Orders showed, y = 105.57x + 858839, R² = 0.2083. Lastly, in the cost analysis of Purchase Department Cost Vs Number of Suppliers the model stated, y = 6393.2x + 434286, R² = 0.5159. Still true, the best model is Purchase Department Cost Vs Number of Suppliers and once the Las Vegas store was removed the R2 drastically increased by 0.2719 giving more evidence to conclude that the highest cost driver is the number of suppliers that CWWR are using all throughout their stores. Seen in Chart 3 the regression model shows the correlation of the cost driver to the department in which the data points give a linear appearance proving the connection. In efforts to bring these cost drivers down the conclusion to cut some of the suppliers from stores there would be a drastic decrease in the departments costs. Also, another idea in order to cut down the costs of Purchasing Departments would be to reduce the number of departments as a whole and create a new system in which near by stores used the same Purchasing Department along with a multi-level management team to approve all
