Assume that a customer shops at a local grocery store spending an average of $250 a week, resulting in the retailer earning a $15 profit each week from this customer. Assuming the shopper visits the store all 52 weeks of the year, calculate the customer lifetime value if this shopper remains loyal over a 10-year life-span. Also assume a 6 percent annual interest rate and no initial cost to acquire the customer. This customer yields $ per year in profits for this retailer. (Round to the nearest dollar.)
