In supply (and demand) problems, y is the number of items the supplier will produce (or the public will buy) if the price of the item is a. For a particular product: The supply equation is: y = 3x+442 The demand equation is: y =-5x+610 Solve this system of equations to determine the point at which the two lines intersect. Give your answer as an ordered pair. The two lines intersect at What is the selling price when supply and demand are in equilibrium? When supply and demand are in equilibrium, the selling price per item is $ What is the number of items in the market when supply and demand are in equilibrium?
