The concentration \(p\) (in \(\mu g/dL\) i.e., micrograms/deciliter) of a hormone, as a function of time \(t\) (in hours) is governed by the following differential equation for \(t \geq 0\)
\[ \frac{dp}{dt} = e^{-0.1t} - 0.1\, p \]
If \(p(0) = 20\ \mu g/dL\), then \(p(10) =\) \(\mu g/dL\). (Round off to one decimal place)
