A reservoir is filled with 1 billion cubic feet of polluted water that initially contains 0.6% pollution. Every day 400 million cubic feet of clean water enters the reservoir and the well-mixed solution flows out at the same rate. When, in days, will the pollutant concentration in the reservoir reach 0.1%
