A chemical spill pollutes a local reservoir. The concentration of the pollutant, $C(t)$ (in parts per million, ppm), at time $t$ (in days) after the initial spill is modelled by the function $$C(t) = 15e^{-0.1t} - 5e^{-0.2t}$$. Local authorities are using an environmental cleanup process to reduce the pollutants.
a. Determine the initial concentration of the pollutant in the reservoir.
