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.  Set up an equation for the low level of 50 milligrams being reached after dose was given and provide a graphing method to find how long until the drug reaches a level of 50 milligrams. Round to 2 decimals.
