Check = X dollars.

Spent: X/2 + 6,

BAL = X - (X/2 + 6) = X/2 - 6.

SECOND TRIP

Spent: 1/2(X/2 - 6) + 2 = X/4 - 1.

BAL = (X/2 - 6) - (X/4 - 1) = X/4 - 5.

THIRD TRIP

Spent: 1/2(X/4 - 5) = X/8 - 5/2.

BAL=(X/4 - 5) - (X/8 - 5/2) = X/8 - 5/2

X/8 - 5/2 = 6,

Multiply both sides by 8:

X - 20 = 48,

X=48 + 20 = $68 = The original amount.
