Final answer:
The salesperson will earn a commission of 27.23 by selling a couch for 495.
Step-by-step explanation:
To calculate the commission earned by the salesperson, multiply the selling price of the couch (495) by the commission rate (5 1/2% or 0.055).
Commission = Selling Price x Commission Rate
Commission = 495 x 0.055
Commission = 27.23
