In terms of price elasticity of demand, differentiate between perfectly inelastic demand and inelastic demand.

To calculate an elasticity coefficient of demand, we need to Divide the percentage change in the price by the percentage change in the quantity demanded Multiply the percentage change in the quantity demanded by the percentage change in the price Know the slope of the demand curve Multiply the percentage change in the price by the percentage change in the quantity demanded

qD = 100 – 0.5p,  qS = 2p – 20 What is the price elasticity of demand? Classify and interpret it.

Calculate the elasticity of demand when demand falls by 10% due to rise in price by 4%

Use the midpoint method to compute the price elasticity on D1. P $10 B $5 A D1 D2 80 90 100 From point A to point B, the price elasticity is:

On the graph, demand starts at D-Start. Suppose income increases by 50% and the demand curve shifts to D1. Price $10 D1 D-Start D2 80 100 125 Quantity From D-Start to D1, the income elasticity using the endpoint method is:

Am. 112.
