Answer:
 The rate of return is 6.5% .
Explanation:
As given 
Phil bought 700 shares of a company’s stock for $9.29/share. 
He pays a broker a commission of $18 to buy and sell stock. 
After one year, he sold all his shares, which were worth $9.90/share at that time. 
Cost price of the 700 shares of a company = 700 × Cost per share + Commission cost .
Cost price of the 700 shares of a company = 700 × 9.29 + 18 
 = 6503 + 18 
 = $ 6521 
Selling st price of the 700 shares of a company = 700 × Cost per share + Commission cost .
 Selling st price of the 700 shares of a company = 700 × 9.90 + 18 
 = 6930 + 18 
 = $ 6948 

Put all the values in the above 



Rate of return = 6.5% 
Therefore the rate of return is 6.5% .
