Let x = original money
x - 25 - .5(x-25) - [.5(x-25)]/3 = 60
Solve for x.

Original Amt. = $X.
1. Spent: $25.
Bal. = (X-25).
2. Spent: (X-25)/2.
Bal. = (X-25)/2.
3. Spent: (1/3)(X-25)/2 = (x-25)/6.
Bal. = (X-25)/2 - (x-25)/6,
Bal.=3(X-25)/6 - (X-25)/6 = 2(X-25)/6 =
(X-25)/3.
Bal. = (X-25)/3 = $60.
(X-25)/3 = 60,
Multiply both sides by 3:
X - 25 = 180,
X = 180 + 25 = $205. = Original Amt.
