A monopoly water slide has demand of p(Q) = a - bQ, where p is the price per slide ("ride"), Q is the quantity of slides demanded, and a, b > 0. Fixed costs are F = 0 and constant marginal costs are c = c1 + c2, where c is the marginal cost per slide for labor and equipment and c2 is the marginal cost per slide for printing and collecting water slide tickets. Let a >c>0 and c> c>c2 > 0. Now assume a block-pricing strategy where the number of slides in the block corresponds to the quantity where price per slide (pb) equals marginal cost, c. What is the fixed fee (fb) and profits () for the monopoly when using block pricing?
