I have everything solved up until the last part. Can someone please assist in the last step?

Industrial Computers Inc. (ICI) is a rackmount computer manufacturer that produces a number of computers in various sizes to be stacked and stored in an enclosure for industrial use. Production costs for these units varies some depending on price levels, supply chain flow, and other factors. Production of each model must also be balanced with production of other, similar models that use the same production lines. Suppose a company like ICI has the following monthly demand, per unit production costs, and production capacity for one of their models: Holding costs are $40 per unit in ending inventory each moth. Initial inventory is 10 units. Determine how many units this company should produce monthly to meet demand and minimize costs. The initial optimal solution will be $1,222,900 Once you find the optimal solution, use Solver Table to see what happens to monthly production, total production costs, total holding costs, and total cost when initial inventory is increased from 0500 units in increments of 50
