The amount of salt present in a lake is decreasing at an average rate of 6% every 3 years. If the amount of salt is known to be 800 kg in 2017, which of the following can best predict the amount of salt present in the lake, in terms of n, the number of years after 2017? A. S(n)=800(0.94)3n​ B. S(n)=800(0.94)3n C. S(n)=800−0.06n D. S(n)=800(0.06)n
