The midpoint method for calculating percentage change is given by the formula: [(Q2 - Q1) / ((Q2 + Q1) / 2)] * 100, where Q1 and Q2 are the initial and final quantities, respectively. Without the specific quantities provided in the question, we can't calculate the exact numbers, but the correct approach involves using the midpoint method formula. Given that choice A is correct, it implies that when applying the midpoint method to the change in quantity demanded as the price falls from $10 to $9, the result is a 22.2 percent increase in quantity demanded. This percentage is typical of the result when the change in quantity is proportionally significant relative to the average quantity before and after the price change.
