Two partners who own Progressive Business Solutions, which currently operates out of an office in a small town near Boston, just discovered a vacancy in an office building in downtown Boston. One of partners favors moving downtown because she believes the additional business gained by moving downtown will exceed the higher rent at the downtown location plus the cost of making the move. The other partner at PBS opposes moving downtown. He argues, "We have already paid for office stationary, business cards, and a large sign that cannot be move or sold. We have spent so much on our present office that we cannot afford to waste this money by moving now." Estimate the second partner's advice not to move downtown.
