1. The problem statement, all variables and given/known data What value of t will make the function = 250? N(t) = 500 / (1+9e^(-5t)) 250 = 500 / (1+9e^(-5t)) 3. The attempt at a solution 1 + 9e^-5t = 2 9e^-5t = 1 t = log1/log(-5)(9e) t = 0 However t = 0 is incorrect because when it is subbed back into the original equation it does not result in 250. How do I solve for the correct value of t?
