Answer:
SUPPLY
Elements of Supply. ... When the price of an orange is 65 cents the quantity supplied is 300 oranges a week. If the price of copper falls from $1.75/lb to $1.65/lb, the quantity supplied by a mining company will fall from 45 tons a day to 42 tons a day.
DEMAND
If movie ticket prices declined to $3 each, for example, demand for movies would likely rise. As long as the utility from going to the movies exceeds the $3 price, demand will rise. As soon as consumers are satisfied that they've seen enough movies, for the time being, demand for tickets will fall.
