Answer: Please refer to Explanation
Step-by-step explanation:
The Grapefruit market will experience an acute shortage of grapefruits because the bad freeze destroyed most of the crop that was going to be supplied.
This shortage in supply will force the price up and therefore lead to a drop in Demand as a lot of people will decide that they can't spend the new amount.
This scenario would lead to an increase in the Equilibrium price because the supply curve will be forced to the left and the new intersect with the Supply curve will be higher. The Equilibrium Quantity will also reduce because of the shortage that is being experienced as a result of a large portion of the grapefruits being destroyed.
In the graph I attached, S2 refers to the supply curve AFTER the bad freezes. Notice how the price went up to P2 and the Quantity dropped to Q2.
