Assume that the demand curve for DVD players shifts to the left and the supply curve for DVD players shifts to the right, but th

kari74 [83]

Answer:

a.both the equilibrium price and quantity of DVD players will decrease

Explanation:

When the amount required or given varies, even if the price stays the same, a move in the demand or supply curve occurs. Changes in the curve of demand mean that the initial relationship of production has shifted so that demand of quantity has a factor apart from cost influenced

A right shift change of the supply curve shows an increase in supply and, on equal footing, the equilibrium price decreases.

Once the demand curve shifts to the left, the demand decreases.
