# PRE-CALC

A drug is eliminated from the body through urine. Suppose that for an initial dose of 10 milligrams, the amount A (t) in the body t hours later is given by A(t) = 10(0.8) t

a) Estimate the amount of the drug in the body 8 hours after the initial dose.

b) What percent of the drug still in the body is eliminated each hour? Explain
