Answer:
b. demand and supply both decrease
Explanation:
Equilibrium quantity can be found at the intersection of the demand and supply curve.
If demand decreases, it means that the demand curve has shifted to the left. It indicates that the demand of consumers have fallen.
If supply decreases, it means that the supply curve has shifted leftward. It indicates that supply has fallen.
The effect on equilibrium price would be indeterminate.
I hope my answer helps you
For equilibrium quantity to fall, their must have been a decrease in both demand and supply (c)
When demand and supply fall, buyers wouldn't be buying as much as they
would have bought and producers will reduce how much they supply, so
definitely quantity will fall but this effect on price cannot be determined.
But, if there is an increase in both demand and supply, buyers or
consumers will have more purchasing power because producers will have
more to supply and their will be an increase in equilibrium output.
Thus, when both supply and demand decrease, equilibrium quantity falls.
