Answer:
b. cannot predict equilibrium price but know that equilibrium quantity will increase.
Explanation:
The options to this question wasn't provided. Here are the options:
a. cannot predict the change in either the equilibrium quantity or equilibrium price.
b. cannot predict equilibrium price but know that equilibrium quantity will increase.
c. predict, that both equilibrium price and quantity will increase.
d. predict, that both equilibrium price and quantity will decrease.
When demand increases, the demand curve shifts to the right. Quanitity demanded increases and price increases.
While when supply increases, the quantity supplied increases and price falls.
The combined effect would be an increase in equilibrium quanitity and an indeterminate effect on price.
