Calculating and Interpreting Elasticity:
a. When the price of oranges increases from \$1.00 per pound to \$1.50 per pound, quantity demanded falls from 500 pounds to 400 pounds. Calculate the price elasticity of demand. elasticity=(1+1.50)/(500+400) x -100/0.5 = – 250/450= -0.556
b. Is the demand for oranges price elastic, inelastic, or unit elastic? Explain. Inelastic because its less than 1
c. Calculate total revenue before and after the price change. How does that relate to the elasticity interpretation? The price will increase total revenue because the reduction of quantity demanded will be smaller than price
Part II. Given the following information, calculate the income elasticity of demand using the midpoint formula.
a. Nancy’s income increases from \$20,000 to \$30,000 and her consumption of spaghetti changes from 10
b. Interpret the result.
Part III. Given the following information, calculate the cross-price elasticity of demand.
a. The quantity of Pepsi purchased rises by 15% when the price of Coca-Cola rises by 30%. Calculate the cross-price elasticity.
b. Interpret the result.
