Price elasticity of demand - is the degree of responsiveness of quantity demanded to a change in price. Ed = percentage change in quantity demanded percentage change in price Percentage change in quantity demanded = change in quantity demanded original quantity demanded Percentage change in price = change in price original price Point Price Quantity Demanded(in kgs) A 30 120 B 35 100 C 40 80 D 45 50 Task # 1 - Compute for the E. from the table above from 1) point A to B and 2) point C to D. Once you have computed the coefficient of elasticity, indicate if elastic, inelastic or unitary. Interpret in a narrative form the result of the computation
