Frederick "Rick" Worrell conducted business as WRL Advertising. However, WRL Advertising was not a legal entity in its own right but rather a trade name for Wingfield, Bennett & Baer, LLC, which is owned and operated by Worrell. Martha J. Musil, an employee of WRL Advertising, placed advertising orders with the Plain Dealer Publishing Company at the direction of her employer. Musil communicated to the Plain Dealer that she was working on behalf of WRL Advertising. WRL did not pay for all of the advertising, and the Plain Dealer sued Worrell and Musil. Shortly after the case was brought, Worrell filed for bankruptcy. Explain whether Musil is personally liable on the contracts.
