Question:
The Initial Concentration of Pollutants in the Pond
Problem: An environmental group estimates that the amount of pollution in a pond will decrease by 10% each month. To determine theconcentration C, of pollutants (in parts per million) after (m) months, the group uses the function C(m) = 23(0.95)m.
(1) to the nearest tenth, what will be the concentration of pollutants in the pond in 5 years?
(2) What was the initial concentration of pollutants in the pond?
