Looking on the website of the US Department of Labor regarding State Minimum Wage Laws I calculated the minimum monthly wage for each state who's Basic Minimum Rate (per hour) is above the federal minmum wage of $7.25 per hour as follow:
Basic Minimum Rate (per hour) x 40 hour work week x 52 weeks / 12 Months = Minimum Monthly Wage.
Basic Minimum Rate (per hour) x 40 hour work week x 52 weeks / 12 Months = Minimum Monthly Wage.
