Question

4. When viewing a graph, you see that there is a

shift in the demand curve to the right for sub sandwiches. This could be the result of

•an increase in the price of subs
•an increase in the price of burgers, a substitute for subs
•an increase in the price of soda, a compliment for subs
•a change in quantity demanded

Answer 1

an increase in the price of burgers, a substitute for subs

Step-by-step explanation:

A substitute good is a good that can be consumed in place of another good. If the price of burgers increases, the demand for burgers would fall and there would be an increase in the demand for the cheaper subs. An increase in demand leads to a rightward shift of the demand curve.

A change in the price of a good leads to a movement along the demand curve for that good.

A compliment good is a good that is consumed with another good. If the price of soda rises, the demand for subs would fall and the demand curve would shift to the left
