Terry has M dollars

Terry spent 5/9 of his money on 3 files and 8 notebooks,

This means that he has     4/9  M   left

and 3/4 of the remaining money on 7 pens.

$$\frac{3}{4}*\frac{4}{9}M = \frac{M}{3}$$     on 7 pens

so  1/3 of his money was spent on seven pens

Each file costs 2/3 as much as a notebook. Each pen costs 40 cents more than a file.
