Explain how will each of the following changes in demand and/or supply affect equilibrium price and equilibrium quantity in a competitive market; that is do price and quantity rise, fall, remain unchanged, or are the answers indeterminate because they depend on the magnitudes of the shifts? Use supply and demand diagrams to verify your answers. a. Demand increases and supply is constant.
b. Supply increases and demand decreases.
c. Demand increases and supply decreases.
d. Demand decreases and supply decreases.

a. If demand increases and supply is constant, there would be a rightward shift of the demand curve. As a result, equilibrium price and quantity would increase

b. An increase in supply would lead to a rightward shift of the supply curve. As a result price decreases and quantity increases. A decrease in demand would lead to a leftward shift of the demand curve. As a result, quantity and price decreases.  Taking these two effects together, equilibrium price decreases and there is an indeterminate effect on equilibrium quantity

c. An increase in demand leads to a rightward shift of the demand curve. As a result, equilibrium price and quantity increases. A decrease in supply would lead to a leftward shift of the supply curve. This leads to a decrease in quantity and an increase in price. Taking these two effect together, there would be an increase in equilibrium price and an indeterminate effect on equilibrium quantity

d.  A decrease in demand would lead to a leftward shift of the demand curve. As a result, quantity and price decreases.  A decrease in supply would lead to a leftward shift of the supply curve. This leads to a decrease in quantity and an increase in price. Taking these two effect together, there would be a decrease in equilibrium quantity and an indeterminate effect on equilibrium price

ok this has nothing to do with business

muslims control the north africa during the period of 1500 up

to 1800. they made a barrier to prevent further european exploration from

entering the africa from the north. however, the dutch ware still able to move

toward the interior with having south africa as one of the routes leading to

the east for trading with asia.
