How much commission does an agent earn from selling a parcel of land 80 feet wide and 200 feet deep?

To understand the correct answer, it's essential to recognize that real estate agents typically earn a commission based on a percentage of the sale price of the property, which is usually established before the transaction. The choices given relate to the commission but calculated in different manners.

When a parcel of land measuring 80 feet wide and 200 feet deep is sold, its total area (in square feet) can be calculated. However, to determine the commission, the question implies that a certain percentage of the total commission or sale price is relevant.

Choosing the option indicating "60% of the total commission" reflects a common approach in real estate transactions where agents may split a commission based on various factors—such as the agreement between agents or brokerages involved in the sale. This option suggests that part of the commission being inquired about depends on an underlying total commission structure, which aligns with typical real estate practices.

In contrast, the other options specifically mention fixed percentages of dollar amounts or total sale prices without providing context to how commission splits operate in real estate, making them less viable in this scenario.

Thus, the selection correctly acknowledges a commission system that includes a shared arrangement among real estate professionals, which is a key aspect of understanding commissions in property transactions.
