The quantity demanded of a certain electronic device is 1000units when the price is $665. At a unit price of $640, demandincreases to 1200 units. The manufacturer will not market any ofthe device at a price of $90 or less. However for each $50 increasein price above $100, the manufacturer will market an additional1000 units. Assume that both the supply equation and the demandequation are linear.
(a) Find the supply equation.
(b) Find the demand equation
(c) Find the equilibrium price.
(d) Find the equilibrium quantity
