After a certain medicine is ingested, its concentration in the bloodstream changes over time.
The relationship between the elapsed time, t, in minutes, since the medicine was ingested, and its
concentration in the bloodstream, Cminute (t), in mg/L, is modeled by the following function:
Cminute(t) = 61 - (0.96)^t
Complete the following sentence about the hourly rate of change in the medicine concentration.
Round your answer to two decimal places.
Every hour, the medicine concentration decays by a factor of
