Question
Assume the marker demand and supply curves for a product in a perfectly competitive market are $P=100-0.50\left(Q_{\mathrm{D}}\right) \quad$ demand curve $P=2+4.0\left(Q_{\mathrm{S}}\right)$ supply curveIf this market converges to equilibrium, the equilibrium price and quantity would bea. $P=108.89$ and $Q=45.56$b. $P=45.56$ and $Q=108.89$c. $P=110$ and $Q=43$d. $P=43$ and $Q=110$
Step 1
The demand equation is \( P = 100 - 0.50Q_D \) and the supply equation is \( P = 2 + 4.0Q_S \). At equilibrium, \( Q_D = Q_S = Q \). Therefore, set the equations equal to each other: \[ 100 - 0.50Q = 2 + 4.0Q \] Show more…

If the equation for the demand curve is Q = 450 - 25P and the equation for the supply curve is Q = -175 + 37.5P, then the equilibrium values for price and quantity are A. P = 4.4 and Q = 340. B. P = 11 and Q = 175. C. P = 12 and Q = 150. D. P = 10 and Q = 200. E. P = 5 and Q = 32
The demand curve for a product is given by $q=100-2 p$ and the supply curve is given by $q=3 p-50$ (a) Find the consumer surplus at the equilibrium. (b) Find the producer surplus at the equilibrium.
Antiderivatives and Applications
Application: Consumer and Producer Surplus
Given the demand curve $p=35-q^{2}$ and the supply curve $p=3+q^{2},$ find the producer surplus when the market is in equilibrium.
