Terry spent 5/9 of his money on 3 files and 8 notebooks, and 3/4 of the remaining money on 7 pens. Each file costs 2/3 as much as a notebook. Each pen costs 40 cents more than a file. What fraction of his money was spent on 7 pens?

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.
