For the equations below, q is the total number of units produced per day by m employees of a manufacturer, and p is the price per unit at which the q units are sold. Find the marginal-revenue product for the given value of m. 400m - m 40 , p= - 0.6q + 20; m = 50 The marginal-revenue product when m = 50 is . (Type an integer or a decimal.)Find the point elasticity of the demand equation for the indicated value of q, and determine whether demand is elastic, is inelastic, or has unit elasticity. p = 39 - 2q; q =4 The point elasticity of the demand equation for q = 4 is n = (Simplify your answer.)
