Final answer:
Net earnings are what remains after all deductions from gross pay. Without details on the deductions, we cannot determine Frank's net earnings from the $300 mentioned.
Step-by-step explanation:
The question concerns the concept of net earnings, which are the amount of money that remains after all deductions are made from the gross pay. In Frank's case, his paycheck is made out for $300, but this does not specify if it is his gross income or his net earnings. The term 'net earnings' typically refers to the amount of money an employee takes home after taxes, insurances, retirement contributions, and other deductions have been subtracted from their gross pay. Without knowing the specific deductions, we cannot accurately calculate Frank's net earnings. It is important to know the context in which the $300 is mentioned to provide a precise answer.
