Given this information and holding everything else constant, how many bagels are supplied when this market is in long run equilibrium?

Assume that the market for bagels is perfectly competitive. Each bagel firm has the same total cost function curves and marginal cost curve. These cost curves for each firm are given by the following equations where q is the number of bagels produced by a firm and P is the price per bagel: Total Cost Curve for a Representative Firm: TC = q*q*q*q + 3 Marginal Cost Curve for a Representative Firm: MC = 4(q*q*q) Suppose that the market demand curve for bagels is given by the following equation where Q is the market quantity of bagels and P is the price per bagel: Market Demand Curve: Q = 100 - 2P Given this information and holding everything else constant, how many bagels are supplied when this market is in long run equilibrium? 100 bagels 94 bagels 92 bagels 98 bagels
