- 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_forwardSuppose a straight-line downward-sloping demand curve shifts rightward. Is the price elasticity of demand higher, lower, or the same between any two prices on the new (higher) demand curve than on the old (lower) demand curve?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_forward
- If 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_forwardJills Sausage Dog Stand projects the following demand for Jills sausage dogs: a. Calculate the price elasticity of demand between 2 and 4. Is demand in this range elastic or inelastic? b. Calculate the price elasticity of demand between 4 and 6. Is demand in this range elastic or inelastic?arrow_forwardSuppose a movie theater raises the price of popcorn 10 percent, but customers do not buy any less popcorn. What does this tell you about the price elasticity of demand? What will happen to total revenue as a result of the price increase?arrow_forward
