Today we’ll be building this model using a sample dataset mobilecarrier.xls, it gives the amount 77 representative are willing to pay per month for each service. The key to this model is to set up a spreadsheet that tells me, for any set of prices for each possible product combination, how much revenue we can obtain from this sample of customers. Then we’ll will use the Solver plug-in to determine the set of prices for the product combinations that maximizes the revenue.
