A partnership has liquidated all assets but still reports the following account balances:

Loan from White

$6,000

Black, capital

3,000

White, capital

(9,000) (deficit)

Green, capital

(3,000) (deficit)

Brown, capital

15,000

Blue, capital

(12,000) (deficit)

The partners split profits and losses as follows: Black, 30 percent; White, 30 percent; Green, 10 percent; Brown, 20 percent; and Blue, 10 percent.

Assuming that all partners are personally insolvent except for Green and Brown, how much cash must Green now contribute to this partnership?
