If No More Pollutants Are Dumped into a Lake, the Amount

question 16

Short Answer

If no more pollutants are dumped into a lake, the amount of pollution in the lake will decrease at a rate proportional to the amount of pollution present. If there are 400 units of pollution present initially and 184 units left after 8 years, use differential equations to find the number of units left after 13 years. Round to 1 decimal place.
