The demand equation for a product is 6' = 400 ’30P + p2 ,Where p is the price per unit and q is the quantity ofunits. Find the point elasticity of demand when p=11. Ifthis price is increased by 2%, what is the approximatechange in demand in % ? Will the changes in the previous problem result in an increase or decrease inrevenue? Explain.
