Karey is prescribed 600 mg of a medication that decays at a rate of 40% per day, d, according to the equation m=600(0.6)d , where m is the amount of medication remaining in his body. noelle takes the same medication five days earlier. the number of milligrams of medication in noelle’s body is about what percentage of the number of milligrams in karey’s body at any time after they have both taken the medication? 3.0% 7.8% 12.9% 46.7%

7.8%

In 5 days' time, the amount remaining is 0.6^5 = 0.07776 times the original amount. Since both people start with the same amount the amount remaining in Noelle's body will be this fraction of that in Karey's body after 5 days have passed.

0.07776 ≈ 7.8%
