Final answer:
The rate of return when 40 shares of StockA, purchased for $15/share, are sold for $690 with a $6 commission is 14%.
Step-by-step explanation:
To calculate the rate of return for the given scenario, we first need to determine the total initial investment and the total amount received from the sale after commission. The student purchased 40 shares of StockA at $15 per share, resulting in a total investment of:
40 shares × $15/share = $600
When the stock is sold for $690, there is a commission of $6, which means the net amount received from the sale is:
$690 - $6 = $684
The net profit is the difference between the sale proceeds and the purchase cost:
$684 (sale proceeds) - $600 (purchase cost) = $84
To find the rate of return, divide the net profit by the initial investment and multiply by 100 to get a percentage:
(Net Profit / Initial Investment) × 100 = Rate of Return
($84 / $600) × 100 = 14%
Therefore, the rate of return when the shares are sold for $690 with a $6 commission is 14%.
