Sam's dad is 4 times older than his son. In 22 years from now, however, he'll only be twice his son's age. How old will Sam be 22 years from now?	Choose the correct answer:
A) 22 years	B) 33 years	C) 44 years	D) 55 years	E) 66 years
At the present,   Sam's age is x.   Sam's father's age is y= 4x.   In 22 years from now,   Sam's age will be x+22.   Sam's father's age will be y+22=2 (x+22).   If we take both equations,   y=4x, and   y+22=2 (x+22),   then   y+22=4x+22=2 (x+22)   4x+22=2x+44   4x-2x=44-22   2x=22   x=11   This is, however, Sam's current age. Since the question is how old he'll be in 22 years from now, the answer 11+22=
