Answer: First question: The correct answer is (c) a change in one of the determinants of demand.
Second question: The correct answer is (d) Sue wants to buy more candy bars at $1 than at $2.
Explanation: Â
1) Some of the determining factors of the demand are the price of the product, the income of the consumer, the price of complementary goods or services, the price of substitute products or the taste of the consumer, among others . Â A change in these determinants produces a shift in the demand curve.
2) The law of demand reflects the relationship between the demand that exists of a good in the market and the quantity of the same that is offered based on the price that is established. At a lower price the demand increases and at a higher price the demand decreases.
