Final answer:
Transportation costs can limit the target markets a manager can serve.
Step-by-step explanation:
Transportation costs can indeed impact a manager's ability to serve target markets. When transportation costs are high, it can limit the geographical area that a manager can reach economically. For example, if a manager has to transport goods over congested street networks or jammed freeways, it will increase costs and reduce profits. On the other hand, if the manager has access to uncrowded freeways or alternative transportation options like rail or water transport, it can make transport more cost-effective and expand the target market that can be served.
