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, 72 mg/dL remain, find an exponential model for the person's blood alcohol level f(t) where t is the time in hours. HINT [See Example 2.] f(t) = Use your model to estimate the person's blood alcohol level after 4 hours. (Round your answer to one decimal place.) mg/dL

Growth Rate Versus Weight Ecologists have studied how a populations intrinsic exponential growth rate r is related to the body weight W for herbivorous mammals. In table 5.2, W is the adult weight measured in pounds, and r is growth rate per year.
