The pesticide DDT was used in the US and later banned. The half-life of DDT is about 15 years. (a) Write an exponential model for the amount of DDT, \( A(t) \), remaining after \( t \) years, if the initial sample is 100 grams. (b) According to your model, how much of the initial sample will remain after 60 years? (c) How many years will it take for the sample to decay to 1 gram?
