Suppose a demand curve has a vertical intercept of (0,80). Suppose a supply curve has a vertical intercept of (0,0). The equilibrium price is $30 and the dollars. equilibrium quantity is 40. The total surplus is O 800 O 1600 O 2400 O 3200

In Figure below, using the supply and demand curves denoted S1 and D1, respectively, Price $150 $100 $75- $50 1 I 50 75 100 O surplus Quantity (thousands) if demand were to increase to D2 and the equilibrium price stayed the same there would be shortage new equilibrium at 75,000 new equilibrium at 100,000 D₂ new equilibrium at 50,000

Air fares are generally lower on Tuesdays and Wednesdays each week. What is a likely explanation for this occurrence? O Supply is relatively variable, and lower demand on these days leads to a lower equilibrium price. O Demand is relatively variable, and lower supply leads to a lower equilibrium price. Lower levels of both supply and demand on these days lead to a lower equilibrium price. Supply is relatively fixed, and lower demand on these days leads to a lower equilibrium price. Demand is relatively fixed, and lower supply leads to a lower equilibrium price. OO

Calculate the consumer surplus for the demand function P=300-3, 2Q when the market price P = R83. O a. 67,8 b. None of the given options is true O c. 5 627 O d. 2 814 O e. 7 358
