After a large number of drinks, a person has a blood alcohol level of 200 mg/dL (milligrams per deciliter). If the amount of alcohol in the blood decays exponentially, and after 2 hours, 112.5 mg/dL remain, find an exponential model for the person's blood alcohol level f(t) where t is the time in hours. Use your model to estimate the person's blood alcohol level after 4 hours. I believe I am supposed to use f(t)=Ab^t but I'm not sure where to go from there
