The quantity demanded x each month of Russo Espresso Makers is 250 when the unit price p is $170; the quantity demanded each month is 1000 when the unit price is $140. The suppliers will market 750 espresso makers if the unit price is $90. At a unit price of $110, they are willing to market 2250 units. Both the demand and supply equations are known to be linear.
What is the supply equation? Equilibrium quantity? equilibrium price?
