Hint: Supppose that Darwin bought x eraser boxes, then he bought \(\frac{4}{5}x\) pencil boxs. (\(x\in N,x>0\)

Because Darwin spent 240 dollars so we have equation:

\(4x+\left(4+6\right).\frac{4}{5}x=240\)

\(\Rightarrow12x=240\Rightarrow x=20\)

So Darwin bought 20 eraser boxes and 16 pencil boxes.

Have a good time :))
