A firm derives revenue from two sources: goods X and Y. Annual revenues from good X and Y are $10,000 and $20,000, respectively. If the price elasticity of demand for good X is -2.0 and the cross-price elasticity of demand between Y and X is 1.5 then a 4 percent price increase will

  • Increase total revenues from X and Y by $800

A firm derives revenue from two sources: goods X and Y. Annual revenues from good X and Y are $10,000 and $20,000, respectively. If the price elasticity of demand for good X is -4.0 and the cross-price elasticity of demand between Y and X is 2.0 then a 2 percent price decrease will

  • Increase total revenues from X and Y by $520

Suppose the equilibrium price in the market is $60 and the marginal revenue associated with the linear (inverse) demand function is $20. Then we know that the own price elasticity of demand is

  • Cannot be determined from the information contained in the question

Suppose the equilibrium price in the market is $100 and the marginal revenue associated with the linear (inverse) demand function is $50. Then we know that the own price elasticity of demand is

  • -1

Suppose that at the equilibrium price and quantity the marginal revenue is -$15 and the price elasticity of demand for a linear demand function is -0.75. Then we know that the equilibrium price is

  • $45

Suppose the equilibrium price in the market is $10 and the price elasticity of demand for the linear demand function at the market equilibrium is -1.25. Then we know that

  • Marginal revenue is $2
