A drug was administered and the function is:  N(t) = 200(0.85)^(x-1), which represents the amount of drug available after each hour since the medication was given. The drug is 85% as effective as the previous hour, (x-1) is part of the formula since it takes one hour for the drug to be absorbed in the bloodstream. (t-1 is included in the formula since it takes one hour for the drug to be absorbed in the bloodstream). How long will it take for this initial dose to reach 50 milligrams? Provide an algebraic equation to show how you solved this problem.
