Answer:
The answer is: $2,700
Step-by-step explanation:
The house sold for $180,000 (= 90% x $200,000).
The total commission was $9,000 (= $180,000 x 5%), split in half between listing office and selling office.
The selling broker received his $4,500 commission, and then h paid his selling associate 60% of it.
The selling associate received a $2,700 commission (= 60% x $4,500)
