A chemical was introduced into a large swimming pool to determine if it would affect the amount of algae in the pool. In each case below, write a formula for K(t), the kilograms of algae in the pool t days after the chemical was introduced. Assume there was 70 kilograms of algae in the pool at t = 0 . Notice that the independent variable is t, not x. (a) the kilograms of algae decreased at a continuous rate of 3% each day. K(t) = (b) the algae decreased by 27 kilograms every 3 days. K(t) =
