**Henry**, Saturday, August 20, 2011 at 2:34pmOriginal 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.
