Using 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.
Prove that price elasticity of demand is not the same as the slope of a demand curve.
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?
Suppose 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?
