Understand that a demand curve shifts to the right when, at every price, consumers want to buy more of the good than before.
Recall that a decrease in population typically reduces the number of buyers, which would shift demand to the left, not right.
Recognize that a decrease in the price of a substitute good (like pretzels) makes the substitute more attractive, causing demand for potato chips to decrease, shifting the demand curve to the left.
Know that an increase in consumer income increases demand for normal goods, shifting the demand curve to the right because consumers can now afford to buy more at each price.
Remember that a decrease in the price of potato chips causes a movement along the demand curve (change in quantity demanded), not a shift of the demand curve itself.
