-----------------
Changed Peter to John to use initials.
---
J + P + S = 825
---
1/3 of John's money was $15 more than 1/4 of Paul's money.
J/3 = P/4 + 15
---
Paul had 2/3 as much as Simon
P = 2S/3
==================
Sub for P
J + P + S = 825
J + 2S/3 + S = 825
J + 5S/3 = 825
---
J/3 = P/4 + 15
J/3 = S/6 + 15
J = S/2 + 45
----
J + 5S/3 = 825
S for J
S/2 + 45 + 5S/3 = 825
13S/6 = 780
----
Solve for S, then for J, etc
