Final answer:
REALTOR Peri can assume she will receive her commission if the real estate deal closes, as this is the standard practice for realtor commissions.
Step-by-step explanation:
The subject in question is related to real estate transactions and the commission of the realtor. When REALTOR Peri is informed that her client's offer was accepted, she can safely assume that she will receive a commission if the deal closes. This is the typical arrangement in real estate transactions where the commission is contingent upon the closing of the sale, and it is usually outlined in the listing agreement. It is neither higher than usual without specific agreement to that effect, guaranteed regardless of the deal closing, nor paid by the buyer unless otherwise agreed upon.
