10. Suppose that Farmers' Bank wishes to serve the nine customer clusters as shown in Figure 13-19. It has proposed locating a branch (A) at coordinates X = 20, Y20. A competing branch (B) is located at coordinates X2 = 40, Y = 30. Farmers' Bank is to be a full-service branch with a relative size (attractiveness) index of 1. The competing branch is a partial-line facility (no ATM, no drive- through capabilities) with a size index of 0.7. The travel time for customers to a bank is approximated as T(hours) = D/50, where D = distance in miles. The average customer generates $100 in gross annual revenue for a bank. The
