You can put this solution on YOUR website! Maria is four times older than Marty. The sum of their age is 55 years. How old are they?
-----------
1 time older --> 100% older = 2 times as old.
2 times older --> 200% older = 3 times as old.
3 times older --> 300% older = 4 times as old.
4 times older --> 400% older = 5 times as old.
=================
Maria = 5*Marty
Maria + Marty = 55
Sub for Maria in eqn 2.
5*Marty + Marty = 55
Marty = 55/6 years
---
Maria = 275/6 years
