The price elasticity of demand for drangles is given by: E(p) = (% change in quantity demanded)/(% change in price) Using the formula, we can find the elasticity at the given price of $19 by calculating the first derivative of the demand function with respect to price: D'(p) = ^-² - (p + 1)^-²P0 At p = 19: D'(19) = -4.75 Plugging into the elasticity formula: E(19) = (-4.75/19) * (19/(p + 1)) = -0.25/(p+1) Evaluating at p=19: E(19) = -0.25/20 = -0.0125 = -1.90 Therefore, the answer is E.
