A yeast culture is growing at the rate of W'(t) = 0.3 e 0.l grams per hour. If the starting culture weighs 3 grams, what will be the weight of the culture, W(t), after t hours? After 8 hours? . . . The weight of the culture after t hours will be W(t) = The weight of the culture after 8 hours will be grams. (Round to the nearest hundredth as needed.)
