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, $C_{\text{minute}}(t)$, in $\text{mg/L}$, is modeled by the following function: ###$C_{\text{minute}}(t)=61\cdot (0.96)\^{\Large t}$ **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 $\ $ [[☃ math-keypad 1]].
