Answer: Ashley has $20
Chau has $15
Rueben has $40
Explanation:
Let x represent the amount that Ashley has.
Let y represent the amount that Chau has.
Let z represent the amount that Rueben has.
Ashley,chau, and reuben have a total of $ 75 in their wallets. This means that
x + y + z = 75- - - - - - - - -- - -1
Chau has $5 less than ashley. This means that
y = x - 5
Reuben has 2 times what ashley has. This means that
z = 2x
Substituting y = x - 5 and z = 2x into equation 1, it becomes
x + x - 5 + 2x = 75
4x = 75 + 5 = 80
x = 80/4 = 20
y = x - 5 = 20 - 5
y = 15
z = 2x = 2 × 20
z = 40
