Solve the problem. In a certain memory experiment, subject A is able to memorize words at a rate given by dm/dt = -0.003t² + 0.4t (words per minute). In the same memory experiment, subject B is able to memorize at the rate given by dM/dt = -0.009t2 (words per minute). How many more words does subject B memorize from t=0 to t = 19 (during the first 19 minutes)?
