represents the amount of medicine in the body at some time after it is administered. To find the time, we need more information about the decay or absorption rate of the medicine. The expression is a typical form for exponential decay, where the base
represents a reduction or decay factor over time.
If you have additional information about the decay rate or half-life of the medicine, we can use that information to determine the time it takes for the amount of medicine to reach this level. Without such information, we can't determine the specific time.
