Final answer:
BadCo is liable to Lisa for the payment of overtime wages under the FLSA.
Step-by-step explanation:
Under the Fair Labor Standards Act (FLSA), overtime wages are typically paid by the employer to eligible employees. In this case, Lisa was placed with BadCo by FedCo, a staffing firm. However, Lisa worked with BadCo for a total of 43 hours. Therefore, BadCo, as Lisa's employer during those hours, would be liable to pay Lisa overtime wages if she is eligible under the FLSA.
