Gilberto's profit is maximized when he produces shirts. When he does this, the marginal cost of the last shirt he produces is $ , which is than the price Gilberto receives for each shirt he sells. The marginal cost of producing an additional shirt (that is, one more shirt than would maximize his profit) is $ , which is than the price Gilberto receives for each shirt he sells.
