Soon after taking an aspirin, a patient has absorbed 300 mg of the drug. if the amount of aspirin in the bloodstream decays exponentially, with half being removed every 2 hours, find, to the nearest 0.1 hour, the time it will take for the amount of aspirin in the bloodstream to decrease to 125 mg.

P(t)=P(0)e^-kt
For half-life:
.5=e^-2k
ln .5=ln e^-2k=-2k ln e=-2k
