When sold for $723.00, a certain desktop has an annual supply of 123 million computers and an annual demand of 156 million computers. When the price increases $852.00, the annual supply increases to 145 million computers, and the demand drops to 138 million computers.NOTE: Round slope and vertical intercept to 4 decimal places and use those rounded values to the end.(a) Assuming that the supply and demand equations are linear, find the supply and demand equations.Supply Equation p =Demand Equation p=(Note: The equations should be in the form p = mg + b where p denotes che price (in dollars) and q denotes the quantity (in billions). The slope and y-intercept should beaccurate to two decimal places).(b) Find the Equilibrium price and quantity.Equilibrium price p =Equilibrium quantity q=(Note: The equilibrium price and quantity should be accurate to two decimal places, and the equilibrium price should include a dollar sign).
