The rate of return is 22.6% .

Option (A) is correct .

Step-by-step explanation:

As given

Nichole bought 500 shares of a company's stock for $8.24/share. \

she pays a broker a commission for $20 to buy and sell stock.

After one year she sold all of her shares which were worth $10.10/share at that time.

Cost price of the 500 shares = 500 × Price per share + Commission price

                                                 = 500 × 8.24 + 20

                                                 = 4120 + 20

                                                 = $4140

Selling price of the 500 shares = 500 × Selling price per share + Commission price

                                                     = 500 × 10.10 + 20

                                                     = 5050 + 20

                                                     = $ 5070

Formula

Rate of return  = 22.6%

Therefore the rate of return is 22.6% .

Option (A) is correct .
