Chapter 6.5, Problem 6TE

Absorption OF Drugs Jane took 100 mg of a drug in the morning and another 100 mg of the same drug at the same time the following morning. The amount of the drug (in mg) in her body t days after the first dose was taken is given by

$\text{A}(\text{t})=\{\begin{array}{ll}100{\text{e}}^{-1.4\text{t}}\hfill & if\text{ 0}\le \text{t}\text{ < 1}\hfill \\ 100(1+{\text{e}}^{-1.4}){\text{e}}^{-1.4\text{t}}\hfill & if\text{t}\ge 1\hfill \end{array}$

Find the average amount of the drug in Jane’s body over the first 2 days.
