Calculator allowed

Use the displayed rate model and units

The ink level in a printer reservoir changes at the rate \(R(s)=4\,s + 2\) in millimetres per minute

Time \(s\) is measured in minutes

At time \(0\), the ink level is \(80\) millimetres

\[s\in\left[0,\;3\right]\]

Give an exact answer

(a)1 mark
