Answer: Some employers and workers will agree on a wage less than $20 and not report the wages to the government; black market
Step-by-step explanation: When the minimum wage is set above the equilibrium wage it leads to a surplus of labor in the market. There are more job seekers than the firms demand at the minimum wage of $20. Thus, the only possible option will be that some employers and workers will agree on a wage less than $20 and not report the wages to the government. When this happens it leads to black marketing. Black market is an underground economy the transactions of which are not reported to the government.
