When the price of ketchup rises by 15 percent, the demand for hot dogs falls by 1 percent. a. Calculate the cross-price elasticity of demand. Instructions: Enter your response rounded to two decimal places. If you are entering any negative numbers be sure to include a negative sign (-) in front of those numbers. Cross-price elasticity of demand: b. Are the goods complements or substitutes: c. In the original scenario, what would have to happen to the demand for hot dogs for us to conclude that hot dogs and ketchup are substitutes? The demand for hot dogs would have to decline. The demand for hot dogs would have to remain unchanged. The demand for hot dogs would have to rise.

Suppose that 50 hot dogs are demanded at a particular price. If the price of hot dogs rises from that price by 5 percent, the number of hot dogs demanded falls to 48. Using the midpoint approach to calculate the price elasticity of demand, it follows that the A) demand for hot dogs in this price range is unit elastic B) price increase will decrease the total revenue of hot dog sellers. C) price elasticity of demand for hot dogs in this price range is about 1.22 D) price elasticity of demand for hot dogs in this price range is about 0.82

If a 5 percent fall in the price of chocolate sauce increases the quantity demanded of chocolate sauce by 10 percent and increases the quantity of ice cream demanded by 15 percent, calculate the a. Price elasticity of demand for chocolate sauce. b. Cross elasticity of demand for ice cream with respect to the price of chocolate sauce.
If the price elasticity of demand for Big Macs is -1.2 and the price increases by 10%, the quantity of demand will decrease by 12%.
