Market demand is given as Qd = 200 – 3P. Market supply is given as Qs = 2P + 100. In a perfectly competitive equilibrium, what will be price and quantity? Price will be $20 and quantity will be 140. Price will be $50 and quantity will be 260. Price will be $100 and quantity will be 300. Price will be $140 and quantity will be 380.

The demand and supply for a product is given by: Qd: 300-5P Qs: 3P-100 Suppose the government imposes a tax T=$16 Calculate: A) Consumer surplus after tax B) Producer surplus after the tax C) Government Revenue D) Deadweight Loss

Demand Equation: QD = 250 − 5P Supply Equation: QS = 10 + 3P

Demand Equation: QD = 250 − 5P Supply Equation: QS = 10 + 3P 1. When P = 5, what is the elasticity of supply? 2. What is The equilibrium price? 3. At the equilibrium price (from Question 2), what is the Consumer Surplus equal to? 4. Suppose the government imposes a tax of of $8 per unit sold of the good. How much of the tax does the consumer pay (per unit)?
