For each of the piece-rate workers below, determine gross pay. If the employees have a standard 37.5-hour workweek, what is their effective hourly rate (the gross pay/37.5 hours)? Based on FLSA minimum wages, what is the minimum wage they must receive each week? If they are not receiving the FLSA minimum wage for the pay period, what is the difference that must be paid by the employer? If not, what is the difference between gross pay and minimum that the employer must pay?
