A stockbroker earns a commission by a flat fee for each transaction as well as a fee per share. On a particular transaction, the stockbroker sold 5,000 shares to a client at a rate of $0.01 per share. The cost of the transaction totaled $57.50. Which of the following equations describes the cost of this transaction in terms of shares sold?A.y = 0.01xB.y = 0.01x + 7.5C.y = 0.01x + 4,999.425D.y = 0.01x + 5,000

Answer:Option B. y = .01x + 7.5Step-by-step explanation:If a stock broker earns a commission by a flat fee for each transaction as well as a fee per share.Let the commission on each share charged by the stock broker is x.Selling price of 5000 shares + total fees of broker = Cost of the transaction5000×.01 + Fees = 57.50Fees = 57.50 - 50 = $7.50Now we can form the equation which represents the cost of this transaction  asy = .01x + 7.5Therefore option B is the correct answer.

Clearly, alternative By = 0.01x + 7.5y = (0.01)*5000 + 7,5y = 50 + 7.5y = 57.50
