Please help with this review problem. I need step by step showing your work so I can study. PLEASE answer ALL problems and letters. I WILL GIVE GOOD RATING!!!

a) 4. Labor Markets, Minimum Wages, and Wage Subsidies: Consider a perfectly competitive labor market with a market supply curve L = 100w And with a market demand curve L = -50w + 450 b) Solve for the equilibrium level of the wage and of employment (L). (5) c) Suppose that a minimum wage of S4 is imposed in this market. How much labor will be employed? What will be the excess supply of labor? (5) d) Forget the minimum wage. Suppose instead the government will provide a subsidy to firms for every unit of labor they employ, reducing their cost per unit of labor by the amount of the subsidy. Now, the labor demand curve is L = 50(w s) + 450 where \"s\" is the amount of the subsidy. e) Suppose the government wants to set this subsidy to the amount necessary to raise the equilibrium wage to $4. How big should this subsidy be? How much labor is employed under this scheme? (5) f) Graph your results show and label the labor supply curve, the original labor demand curve, the subsidized labor demand curve, the minimum wage, and the resulting levels of employment in each case
