A chocolate factory produces molten chocolate by adding cocoa powder and cocoa butter to
several other ingredients. The 100 L tank initially only contains 25 L of non-cocoa liquid. From
time t = 0, cocoa butter is added at 0.6 L/min, while cocoa powder is added at 0.4 L/min. The
chocolate flows out of the bottom of the tank at a rate of 0.4 L/min. You may assume the liquid
in the tank is always mixed evenly.
