Question 286421: The equations S=5000-200x and D=9500-100x express the supply S and the demand D, respectively, for a popular compact disc brand in terms of its price x (in dollar)
A) Graph the equations on the same coordinate ststem.
B) What happens to the supply as the rice increase?
C) What happens to the demand as the price increase?
D) The price at which supply and demand are equal ia called the equilibrium price. What is the equilibrium price?

You can put this solution on YOUR website! The equations S=5000-200x and D=9500-100x express the supply S and the demand D, respectively, for a popular compact disc brand in terms of its price x (in dollar)
A) Graph the equations on the same coordinate system.
B) What happens to the supply as the rice increase?
S decreases because the slope is negative.
---------------------------------------------------
C) What happens to the demand as the price increase?
D decreases because the slope is negative.
---------------------------------------------------
D) The price at which supply and demand are equal ia called the equilibrium price.
What is the equilibrium price?
Solve 5000-200x = 9500-100x for "x"
