The demand equation for a product is q = 400 -50p + p- where p is the price per unit (in dollars) and q is the quantity of units demanded (in thousands). Find the point elasticity of demand when p = 13. If this price of 13 is increased by 15%, what is the approximate change in demand? The point elasticity of the demand equation for p = 13 is n = (Simplify your answer.) If this price of 13 is increased by 2 2% , the approximate in demand is % (Round to two decimal places as needed.) increase decrease Next O W N T 46.F ENG 4:11 PM 2021-10-31
