When income increases by 10 percent (or numerically, 0.1), quantity demanded moves by 168 units. Assuming the income elasticity of demand is 4. What is the original quantity demanded? (assuming further that this is the point elasticity relative to the original point.) Please make sure you give a numerical answer with no units and/or space or period (.) or comma (,) before or after your answer. Enter your answer here

(Calculating Price Elasticity of Demand) Suppose that 50 units of a good are demanded at a price of Si per unit. A reduction in price to $0.20 results in an increase in quantity demanded to 70 units. Using the midpoint formula, show that these data yield a price elasticity of 0.25. By what percentage would a 10 percent rise in the price reduce the quantity demanded, assuming price elasticity remains constant along the demand curve?

Suppose that your demand schedule for pizza is as follows: a. Use the midpoint method to calculate your price elasticity of demand as the price of pizza increases from 8 to 10 if (i) your income is 20,000 and (ii) your income is 24,000. b. Calculate your income elasticity of demand as your income increases from 20,000 to 24,000 if (i) the price is 12 and (ii) the price is 16.

What is the formula for the income elasticity of demand?

What is the formula for line cross-price elasticity of demand?

What is the formula for calculating elasticity?

What is the price elasticity of demand? Can you explain it in your own words?

Suppose Sally buys exactly five bars of English toffee each week, regardless of whether the toffee bars are regularly priced at 1 or on sale for 0.50. Based on this information, what is Sallys price elasticity of demand for English toffee in this price range? a. 0 b. 1 c. Infinity d. Cannot be determined.

Why is the demand curve with constant unitary elasticity concave?

Economists define normal goods as having a positive income elasticity. We can divide normal goods into two types: Those whose income elasticity is less than one and those whose income elasticity is greater than one. Think about products that would fall into each category. Can you come up with a name for each category?
