Final answer:
The agency made $18,480 on the house, while the agent earned $5,544 in commission.
Step-by-step explanation:
To find out how much the agency made on the house, we need to calculate their commission.
The commission rate for the agency is 5.5% of the selling price, which is $336,000.
So, the agency made 5.5% of $336,000, which is 0.055 * $336,000 = $18,480.
Next, to find out how much the agent earned in commission, we need to calculate their commission rate.
The agent's commission rate is 30% of the amount the agency gets.
So, the agent earned 30% of $18,480, which is 0.3 * $18,480 = $5,544.
