**Henry**, Tuesday, September 18, 2012 at 9:09pm$X = Amt. raised.

X/2 = Amt spent for meds.

Bal = $X/2.

1/4 * X/2 = X/8 spent for tents.

Bal = X/2 - X/8 = 4x/8 - X/8 = 3X/8.

2/3 * 3X/8 = 6X/24 = X/4 Spent for water

purification.

Bal = 3X/8 - X/4 = 3X/8 - 2X/8 = X/8.

X/8 Spent for shipping.

Bal = X/8 - X/8 = $0.

a. X/4 = $400.

X = $1600 = Amt. raised.

X/2 = 1600/2 = $800 For Meds.

X/8 = 1600/8 = $200 ForTents.

X/8 = 1600/8 = $200 For Shipping.

b. X/4 = $400.

X = $1600 Raised.
