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 :))

1 eduro =100 eurecents , so Helga has :
5x100=500 eduro
the cost of 5 notebooks are:
80x5=400
when she buy 5 notebooks money she has is
500-400=100 eurecents
one pencil costs 30 eure so 3 pencils cost are : 30x3=90 eure
So Helge can afford to buy 3 pencils and she plainti 10 eure
