Using and to calculate the effect of a price decrease on Q^d and total revenue for the following elasticities:

		Quantity Demanded	Total Revenue
1. = 0	Perfectly Inelastic	decrease constant increase	decrease constant increase
2. < 0	Inelastic	decrease constant increase	decrease constant increase
3. = 1	Unitary Elastic	decrease constant increase	decrease constant increase
4. > 1	Elastic	decrease constant increase	decrease constant increase
5. =	Perfectly Elastic	decrease constant increase	decrease constant increase
