Question

The price of peanut butter increases from $3.50 to $4.00 per jar, and the quantity of jelly demanded falls from 35 jars to 28 jars. Using the midpoint formula, calculate the cross-price elasticity of demand. Report your answer to two decimal places.

Answer #1

The cross-price elasticity of demand for peanut butter with
respect to the price of jelly is -0.3. a. Are they complement or
substitute products? Explain your answer. (5pts.) b. If we expect
the price of jelly to decline by 15%, what is the expected change
in the quantity demanded for peanut butter? (Show your
calculations) (10pts.)Immersive Reader (15 Points)

Suppose the price of apples increases from $20 to $28, and in
response quantity demanded decreases from 100 to 84. Using the
mid-point formula, what is the price elasticity of demand? (Note:
your answer should be correct to two decimal places; and be sure to
express your answer as a positive number.)

The price of a new portable CD player falls from $100 to $90.
The quantity of CD players demanded rises from 15,000 per year to
20,000 per year. Use the midpoint formula to calculate the price
elasticity of demand for portable CD players. Is the demand
elastic, inelastic, or unit elastic?

Consider the following combinations of price and quantity
demanded for an unnamed good. These questions ask you to perform
several percentage change an elasticity calculations. When
calculating percentage change, some questions ask you to use the
traditional formula and some ask you to use the midpoint formula.
For clarity, these two formulas are given below. The values you
calculate should be between -100 and 100 (not -1 to 1). Please
include the sign (if negative) in all of your responses....
