Question 1: The price of the good X rises from $1.30 to $1.40. Calculate the price elasticity of demand by using the mid-point method.

Question 2: How do you explain the answer in question 1 in plain English to someone who is not an economics student?

Question 3: What are the factors that can make this demand less elastic?

Question 4: Calculate the price and quantity effects of this increase in price of X.

Question 5: Is it possible to raise more revenue by increasing the price of good X from $1.3/unit to $1.4/unit? Explain your answer by using the price and quantity effects.

Question 6: Assume that the price of good X is $1.3/unit. An increase in the price of good Y from $3 to $5 shifts the demand curve for the good X rightwards. With the price of good X constant at $1.3/unit, the quantity demanded for X increases from 7000units to 8000units. Calculate the cross price elasticity of demand between X and Y. What type of relationship do you find between goods X and Y?

Question 7: Assume that the price of good X is $1.3/unit. An increase in the price of good Z from $3 to $5 shifts the demand curve for good X leftwards. With the price of good X constant at $1.3/unit, the quantity demanded for good X declines from 7000units to 5000units. Calculate the cross price elasticity of demand between X and Z. What type of relationship do you find between goods X and Z?

Question 8: Assume that the price of good X is $1.3/unit. An increase in the income of the consumer from $2000 to $2500 shifts the demand curve for good X shifts rightwards. With the price of good X constant at $1.3/unit, the quantity demanded for good.
