Answer:
1) Decrease
2) Greater than
3) Decreases
Explanation:
If a good has elastic demand it means that when the price of a good changes by 1% the quantity demanded of the good changes by more than 1%. So if the demand for good x is elastic it means when the price of good x rises by 1 % than the demand for good x decreases by more than 1 percent. Therefore the total revenue of a elastic good decreases when price is increased and the total revenue increases when price decreased.
