Answer:
a. Elastic, decrease
b. Unit elastic, remain same
c. Inelastic, increase
Explanation:
a. The demand here is elastic as it is more than 1. This implies that an increase in price will cause the quantity demanded to decrease more than proportionate. This will cause total revenue to decrease.
b. The demand here is unit elastic as it is equal to 1. This means that an increase in price will cause the quantity demanded to decrease by the same proportion. As a result, the total revenue will remain the same.
c. The demand here is inelastic as it is less than 1. This means that an increase in the price will cause the quantity demanded to decrease by less than proportionate. As a result, the total revenue will increase.
