Suppose that you are the owner of the Original Italian Pizza restaurant chain and would like to predict the sales of your specialty, deep-dish pizza. You have gathered data on the monthly sales of deep-dish pizzas at your restaurants and observations on other potentially relevant variables for each of your 15 outlets in central Indiana. These data are provided in the file assignment 1. Analyse the results in Excel and find the best combination of advertising and pricing to obtain the highest profit. (Variable cost of deep-dish pizza is around $5 per pizza in all your locations.) Explain the analyses you executed and the results you obtained. Please also upload the Excel file containing your analyses.
