5. The apple growers (in relation the above problem) want to increase their Total Revenue by increasing the price of apples. In which of the following cases will the total revenue actually increase as a result of the price rise? (Hint: Is the demand elastic or inelastic in each of the following cases?) (2 points)

a. Elasticity of demand is 0.6

b. Elasticity of demand is 4.6

c. Elasticity of demand is 100

d. There is not enough information to answer.

Answer #1

1. Option d

Price elasticity of demand = % change in quantity demanded/% change in price

= -100/20%

Change in quantity demanded is needed in percentage change

2. Option c

As supply doesn't respond to changes in price

3. Option a

As quantity demanded doesn't respond much for changes in price

4. Option d

All of the reasons would contribute to reduced supply and increase in price

5. Option a

Total Revenue would increase when the demand is inelastic as quantity demanded doesn't change much for the increase in price.
