Answer 1

Answer- 1 False.

Market Demand curve will not shift leftwards, since it is a price decreases. There will be movement along demand curve not shift. Contraction of demand will happen in this scenario.

Answer-2 The costs of producing a single Blue- ray player increases.

Supply of a commodity is affecting by costs. If cost of production increases, less of the commodity is supplied at it's existing price, there will be a leftward shift.

Answer-3 All of the above are expected to occur when Blue-ray movies become significantly cheaper.

Since it's price has reduced so more of Blue-ray movies will be demanded, and blue- Ray player and blue ray movies are complementary hence players' demand will also rise. DVD player is substitute, it's demand will fall.

Answer- 4 demand and supply both increase.

Equilibrium quantity rises when both inceases.
