Answer:
May 06, 2018 · Real estate agents, car dealers, and pharmaceutical sales representatives earn commissions that are a percentage, or part, of sales. For example, a real estate agent might earn a portion of the selling price of a house that she helps a client purchase or sell. A car salesperson earns a portion of the selling price of an automobile that she sells.
$391 is earned by Mrs. Hollern for selling a necklace that costs $4,600
Since a commission of 8.5%(0.085) is earned for each jewelry sold, hence the total commission (y) for selling x worth of jewelry is:
y = 0.085x
Hence for selling $4600, the commission earned is:
y = 0.085(4600)
y = 391
Hence $391 is earned by Mrs. Hollern for selling a necklace that costs $4,600.
