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?

1260 cents (might be wrong, but double checked)

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.
