Answer :
Answer:
a, a downward movement along the demand curve
b. a leftward shift in the demand curve
c. a rightward shift in the demand curve
Explanation:
If the price of caramel topping decreases, there would be an increase in the quantity demanded of the topping. so there would be a downward movement along the demand curve for caramel topping
Icecream and caramel toppings can be regarded as complement goods
Complementary goods are goods that are consumed together
If the price of icecream increase, the quantity demanded of icecream would decrease. because of the decrease in the quantity demanded of caramel toppings, there would be a decrease in the demand for caramel toppings. the demand curve for caramel toppings would shift inwards reflecting the decrease in demand.
caramel and butterscotch ice cream toppings are substitutes goods
Substitute goods are goods that can be used in place of each other.
If the price of butterscotch topping increases, butterscotch topping becomes more expensive and there would be a decrease in the quantity demand for butterscotch topping. consumers would shift to caramel topping. as a result there would be an increase in demand for caramel topping and the demand curve would shift outward.
