The price per unit of labour is $ The minimum cost of producing 1,700 units of output is $ To produce 1,700 units of output at the least cost the firm should use units of labour. The Marginal Rate of Technical Substitution at each cost minimizing equilibrium point is If the firm decides that total cost must not exceed $37,500, the maximum amount of output it can produce is To produce 900 units of output at the least cost the firm should use units of capital
