I am worried about the outlet that has the worst annual sales. I am deciding whether to close down the outlet in the longer term. Using Solver or Goal Seek, create a model to appraise this decision. For an outlet to be retained, it must achieve annual sales of at least 85% of the average outlet sales of the entire chain.

How much must the annual sales in the worst performing outlet increase for it to be retained? What would the total annual sales for the whole chain?
