After alcohol is fully absorbed into the body, it is metabolized with a half-life of about 1.5 hours. suppose you have had three alcoholic drinks and an hour later, at midnight, your blood alcohol concentration (bac) is 0.5 mg/ml. (a) find an exponential decay model for your bac t hours after midnight.

Step-by-step explanation:
Given :
After alcohol is fully absorbed into the body, it is metabolized with a half-life of about 1.5 hours.
Your blood alcohol concentration (BAC) is 0.5 mg/mL.
To Find : Find an exponential decay model for your BAC t hours after midnight.
Solution:
General form of decay model :
Where is the initial BAC
C(t) is the BAC after t hours
k is the decay constant
Now we are given that After alcohol is fully absorbed into the body, it is metabolized with a half-life of about 1.5 hours.
Formula :
Your blood alcohol concentration (BAC) is 0.5 mg/mL..
So,
So,
Hence an exponential decay model for your BAC t hours after midnight is
