How does the supply and demand shift in both the cream and peaches market (left/right)? &multiple choice

The markets for peaches and cream are inter-related. Peaches and cream are complements. The government becomes concerned the market for peaches is about to become over-priced. They place a price ceiling on the market for peaches at the current price. In the TWO graphs below, show the effect of the price ceiling on the markets for peaches and cream if the price of milk (an input for cream) increases. Then answer the questions.

Solution

A rise in price of milk which is an input in cream production lowers the supply of cream at each price.In other words it shifts the supply curve for cream leftwards thus reducing the equilibrium quantity of cream and increasing the equilibrium price of ceam.

Now cream being complement to peaches an increase in price of cream reduces the demand for peaches.Thus shifting the demand curve for peaches leftwards.This leads to an equilibrium quantity lesser than 5000 and an equilibrium price lower than $3.

Thus Q_D = Q_S < 5000 and equilibrium price of peaches less than $3.
