Situation: A 25 gram sample of a substance used for drug research has a k-value of 0.1205. N=N0e^-kt N0 = initial mass (at time t=0) N = mass at a time t K = a positive constant that depends on the substance itself and on the units used to measure time T=time, in days Find the substances half-life, in days. Round your answer to the nearest tenth?
