As the price of good X rises from $10 to $12,the quantity demanded of good Y rises from 100 units to 114 units. are X and Y substitute or complement? What is the cross elasticity of demand?
The quantity demanded for product A increases 8% when the price of product B increases 16% and the other variables remain the same. Calculate the cross elasticity of demand. Products A and B, are they complementary or substitutes? Why? By drawing a graph, show the change in the demand curve for product A as a result of the change in the price of product B.

- The quantity demanded of good X rises from 130 to 145units as income rises from 2,000 to 2,500 a month. What is the income elasticity of demand for good X?arrow_forwardUsing the following equation for the demand for a good or service, calculate the price elasticity of demand (using the point form), cross-price elasticity with good x and income elasticity. Q=82P+0.10I+Px Q is quantity demanded, P is the product price. P1 is the price of a related good, and I is income. Assume that P= $10, I = 100, and Px = 20.arrow_forwardIf the price of a good or service increases and the total revenue received by the seller declines, is the demand for this good over this segment of the demand curve elastic or inelastic? Explain.arrow_forward
- Prove that price elasticity of demand is not the same as the slope of a demand curve.arrow_forwardAs the price of good X rises from RM 10 to RM 12 , the quantity demanded of good Y rises from 100 units to 114 units . Are X and Y subsitutes or complements ? What is the cross elasticity of demandarrow_forwardGood X becomes cheaper to produce, decreasing its price. As a result, the demand for good Y increases. What can you say about the cross-price elasticity between the two goods? Moreover, discuss whether the two goods are substitutes, complements or neither.arrow_forward
- A college raises its annual tuition from $23,000 to $24,000, and its student enrollment falls from 4,877 to 4,705. Compute the price elasticity of demand. Is demand for the college elastic or inelastic? As the price of good X rises from $10 to $12, the quantity demanded of good Y rises from 100 units to 114 units. Are X and Y substitutes or complements? What is the cross elasticity of demand? The quantity demanded of good X rises from 130 to 145 units as income rises from $2,000 to $2,500 a month. What is the income elasticity of demand for good X? The quantity supplied of a good rises from 120 to 140 as price rises from $4 to $5.50. What is price elasticity of supply of the good?arrow_forwardIf goods X and Y are SUBSTITUTES, then which of the following could be the valueof the cross price elasticity of demand for good Y?arrow_forwardThe price of apples rises from $1.00 per pound to $1.50 per pound.

Suppose that Mrs. Baker is currently exhausting her money income by purchasing 10 units of X at a price of $10 each and 8 units of Y at a price of $6 each. The marginal utility of the last unit of X is 30 and for Y is 28. These data suggest that Mrs. Baker should either Three Options: 1. Buy less Y and more X 2. Buy less X and more Y 3. Stay with her current selection. Pick one of the three above options as your answer and justify (explain) your answer below:arrow_forwardAt Mcdonald, as the price of grilled chicken salad increases from $4 to $6 while the quantity demanded of Big Mac rises from 700 to 900 a day. Which of the following is NOT true? A. The cross elasticity of demand is 5/8 B. At Mcdonald, grilled chicken salad and Big Mac are substitutes. C. For every 10% increase in the price of grilled chicken salad, we should expect to see a 6.25% increase in the quantity demanded of Big Mac. D.
