3. Lin is shopping for a couch with her dad and hears him ask the salesperson, "How much is your commission?" The salesperson says that her commission is LaTeX: 5\frac12\%5 1 2 % of the selling price. How much commission will the salesperson earn by selling a couch for $495? How much money will the store get from the sale of the couch?

i. Salesperson's commission = $27.225

ii. Amount for the store = $467.775

Step-by-step explanation:

The commission of the salesperson = of selling price

Price of a couch = $495

Salesperson's commission = of $495

                                             = x 495

                                             = 27.225

Salesperson's commission = $27.225

Amount that the store would get from the sale = selling price - commission

                                                 = $495 - $27.225

                                                 = $467.775

The store would get $467.775 from the sale of the couch.
