Assume that good X is a normal good. Which of the following helps to explain why a decrease in the price of good X increases the quantity demanded of good X? ---- A Good X becomes relatively less expensive than its substitutes, so consumers buy more of good X and fewer of the substitutes B The marginal utility of consuming good X increases as more of good X is consumed.
