If the legal minimum wage rate were set at $15/hour,

A) employment would decline substantially.
B) employment would decline slightly.
C) employment would not be affected.
D) employment would rise slightly.
E) employment would rise substantially.

If the minimum wage rate were set at $15/hour, it would lead to an increase in labor costs for employers. This will lead to a decrease in demand for labor, as it becomes more expensive to hire workers. Employers would be more likely to replace workers with machines or outsource work to countries with lower labor costs. Therefore, employment would decline substantially.
