n my chain of stores, I suspect that my upkeep costs (keeping the store looking clean and trendy to maintain the expectations of my demanding customer base) varies across locations with income (in the 1000s) in the local area and with store square footage (Size). My data are on the Excel spreadsheet that is part of this homework. I am considering buying a competitor's store and adding it to my chain. I want to forecast my costs if the current owner is spending $6550 for the 2000 square foot location with an average income of 140,000 in the area
