Answer:
$8,400
Explanation:
total commission = $300,000 x 8% = $24,000
50% co-brokerage split = $24,000 x 50% = $12,000
Walt's commission = $12,000 x 70% = $8,400
the 70% commission split between Walt and his broker means that Walt keeps 70% of the commission and the broker keeps 30%.
total commission is split between the two firms because the Walt's listing was sold by another firm.
