According to Stevenson and Wolfers' Cost-Benefit Principle, what is the relationship between "willingness to pay" and the decision to purchase a good? Group of answer choices You should purchase the good if your willingness to pay is less than the price. You should purchase the good if your willingness to pay is equal to or greater than the price. Willingness to pay is irrelevant to the decision-making process. You should purchase the good only if your willingness to pay is at least twice the price
