You can put this solution on YOUR website! when maria was born her mother was 24 years old.
At maria's birth: mom = maria + 24
---------------------
at present maria's age is 20 percent of her mother age. how old is maria now
Now: maria = 0.20(mom)
---
Substitute for "mom" and solve for "maria"
------------------
maria = 0.20(maria + 24)
maria = 0.2(maria) + 0.2(24)
0.8(maria) = 4.8
maria now = 6 yrs old
