Question 1001273: Tony is four times as old as Janet and half as old as Bill. The sum of three ages is 39 years. How old is each person? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Use t,j, and b for their ages.
t = 4j or j = (1/4)t
t = (1/2)b or b = 2t
t + j + b = 39
Plug in and solve for t.
t + (1/4)t + 2t = 39
(13/4)t = 39
t = 12
From that
b= 24 and
j= 3
