The concentration, C in parts-per-thousand (ppt), of a pollutant in a river during the manufacturing phase of a neighbouring factory is given by the equation 1200r5 ke3t where t is the number of days after the manufacturing phase begins, and k is some C(t) = %D constant. Suppose that the concentration after one day is 2 ppt. How fast (in ppt/day) will the concentration be changing after 2 days? Make sure your answer is correct to at least two decimal places. The answer you obtain should be negative. Do not include units. What is the highest value (in ppt) that the concentration will obtain? Make sure your answer is correct to at least two decimal places. The answer you obtain should be positive. Do not include units.
