A fundraising meeting for Jako, Bula, Jane and Abdi raised $ 108,000. Jako got three times as much as abdi. Jane got two-thirds of Jako's share while Bula got half as much as Jako. How much did Bula receive?

Bula --- x

Jako --- 2x
abdi --- 2x/3
Jane ---- (2/3)(2x = 4x/3

x+2x+2x/3+4x/3 = 108000
times 3
3x + 6x + 2x + 4x = 324000
15x = 324000
x = 21600
