Question 1169328: The ratio of Susan’s money to Tommy’s money is 7:3 If Tom has 48 dollars less than Susan, find how much money each person has. (Algebraic Solution only) Answer by ikleyn(52881) (Show Source):
Susan has 7x dollars; Tommy has 3x dollars.
The governing equation is
7x - 3x = 48 dollars.
which implies
4x = 48
x = 48/4 = 12.
ANSWER. The dollars are 7*12 = 84 (Susan) and 3*12 = 36 (Tommy).
