The demand curve for the commondity is given as `D_(x)=10 +2P` . If slope of the demand curve is given to be (-2), calculate price elaticity of demand for the commodity when demand is 10 units.

The demand curve of a commodity is expressed as D_(x)20 - 2P . If slope of the demand curve is given to be (-2). Calculate price elasticity of demand for the commodity when demand is 10 units.

The demand curve of a commodity is expressed as D_(x)=40-5P . If slope of the demand curve is given to be (-2) , calculate price elasticity of demand for the commodity when demand is 20 units.

The demand curve for the commondity is given as D_(x)=20 -2P . If slope of the demand curve is (-2), calculate price elasticity of demand for the commodity when the price of the commodity is ₹5 per unit.

A unit price elastic demand curve will touch
