David and John shared some money in the ratio 5:2 John received $30 less than David. How much money did John get?

Answer 1

Represent the unknowns. Since the ratio of their money shared is 5 (David) : 2(John),
Let 5x = David's money
Let 2x = John's money
In the problem, John received $30 less than David. Thus,
2x = 5x - 30
Solving,
2x - 5x = -30
-3x = -30
x = 10
Thus,
5x = $50 (David)
2x = $20 (John)
