**Henry**, Monday, October 8, 2012 at 4:28pmSum = $X.

Aaron = 0.4x.

Benny = (0.4x+29).

Charles = (0.4x+29)/3.

a. 0.4x + (0.4x+29) + (0.4x+29)/3 = $X.

Multiply both sides by 3:

1.2x + 1.2x + 87 + 0.4x + 29 = 3x

2.8x - 3x = -116

-0.2x = -116

X = $580.

Charles = (0.4*580+29)/3 = $87.

Charles % = (87/580)*100% = 15.

b. Total = X = $580.
