Answer:
Step-by-step explanation:
Given that,
Ratio of division between the three children is
Abe : Beth : Charlie = 3 : 2 : 7
Total ratio is 3+2+7 = 12
If Charlie receive $120 more than Abe
We want find how much Beth receives
Let the total money be $y
Using ratio
Abe : Beth : Charlie = 3 : 2 : 7
Abe will receive
Abe = ( 3 / 12 ) × y
Abe = y / 4
Beth will receive
Beth = (2 / 12) × y
Beth = y / 6
Charlie will receive
Charlie = (7 / 12) × y
Charlie= 7y / 12
We know that
Charlie will receive $120 more than Abe,
Then,
Abe + $120 = Charlie
(y / 4) + $120 = 7y / 12
Multiply through by 12 to remove the frationc
3y + 1440 = 7y
Collect like terms
1440 = 7y - 3y
1440 = 4y
Divide both sides by 4
y = 1440 / 4
y = $360
So, the total money shared is $360
Then, to find Beth
Beth receive y/6
Beth = y / 6
Beth = 360 / 6
Beth = $60.
