The total utility from three pieces of pizza is calculated by adding the marginal utility of each piece. The first piece gives 25 points, and the second piece increases total utility to 40 points, indicating the second piece itself provides 15 marginal utility points (40 total - 25 from the first = 15). The third piece adds 10 marginal utility points to the total, making the total utility from three pieces 40 + 10 = 50 points.
