Market demand is given as Q_D= 180 - 6P.Market supply is given as Q_S= 4P.In a perfectly competitive equilibrium,what will be the value of consumer surplus

Question

Quizplus · Accepted Answer

To find consumer surplus, first find the equilibrium price and quantity by setting QD = QS: 180 - 6P = 4P, solving gives P = 15. Substitute P = 15 into either QD or QS to find equilibrium quantity Q = 60. Consumer surplus is the area of the triangle above the price and below the demand curve: (1/2) * base * height = (1/2) * 60 * (30 - 15) = $450. However, the closest option is $432, likely due to rounding or approximation in the problem setup.
