13yrs=S ANSWER: Sarah is currently 13 years old.
You can put this solution on YOUR website! When Sarah turns 36 years old, her father will be 62. Currently, Sarah is 1/3 of her father's age. How many years old is Sarah now?
--------
Equations:
s = (1/3)f
----
Father is always 62-36 = 26 years older than Sarah.
------
f = s + 26
-----
Substitute for "f" and solve for "s"::
s = (1/3)(s+26)
3s = s+26
2s = 26
s = 13 yrs (Sarah's age now)
