A product is introduced to the market. The weekly profit (in dollars) of that product decays exponentially 75000 e -0.04.x = . as function of the price that is charged (in dollars) and is given by P(x) Suppose the price in dollars of that product, x(t), changes over time t (in weeks) as given by x(t) = 55+0.95 - t² Find the rate that profit changes as a function of time, P'(t) -0.04(55+0.95t²) 5700te dollars/week How fast is profit changing with respect to time 4 weeks after the introduction. 1375.42 dollars/week
