Samantha's mom is currently three times Samantha's age. Samantha's dad is 3 years older than her mom.
The sum of all three of their ages is 80. How old is Samantha?
~~~~~~~~~~~~~~~~~~~~

Samantha + Mom + Father  = 80.

S        + 3*S + (3*S+3) = 80.

7*S = 80 - 3  ====>  7*S = 77  ====>  S =  = 11.
