(1 point) a tank contains 2500 l of pure water. solution that contains 0.02 kg of sugar per liter enters the tank at the rate 9 l/min, and is thoroughly mixed into it. the new solution drains out of the tank at the same rate. (a) how much sugar is in the tank at the begining? y(0) = (kg) (b) find the amount of sugar after t minutes. y(t) = (kg) (c) as t becomes large, what value is y(t) approaching? in other words, calculate the following limit. lim y(t) = (kg)
