From the schedule provided below calculate the total revenue, demand curve and the price elasticity of demand:

Quantity	1	2	3	4	5	6	7	8	9
Marginal Revenue	10	6	2	2	2	0	0	0	-5

Quantity

Marginal Revenue (MR)

Total Revenue (TR)

Average Revenue (AR) =TR/Quantity

Elasticity of Demand (Ed) = (ΔQ/ ΔP) (P/Q)
