Solution
Percentage method for calculating price elasticity of supply:
Price elasticity of supply refers to the ratio of percentage change in quantity supplied to the percentage change in price.
`e_s = "Percentage change in Quantity Supplied"/"Percentage change in Price"`
`e_s = ((ΔQ)/Q xx 100)/((ΔP)/P xx 100)`
= `(ΔQ)/(ΔP) xx P/Q`
