How do you calculate the time it takes for something to get to 15% of its initial concetration and 1/9th of its initial condition if you are given only its half life?

You can assume that the initial concentration equals 1 and the final concentration you're looking for equals 0.15 when solving the half-life equation for time.

Using the given half-life, we can use the formula 
to calculate the k value. From there, we can use the formula 
to calculate time. [A]t is the concentration remaining after time t.
