Final answer:
To find the total price of the transaction, multiply the number of shares by the price per share. The total price of the transaction is $54,200.
Step-by-step explanation:
To find the total price of the transaction, we need to multiply the number of shares by the price per share. In this case, we have 400 shares of National Semi at 135 1/2. To calculate the price per share, we need to convert 1/2 to its decimal equivalent, which is 0.5. So, the price per share is 135 + 0.5 = 135.5 dollars. Now, we can find the total price of the transaction by multiplying the number of shares (400) by the price per share (135.5).
Total price of the transaction = 400 * 135.5 = 54,200 dollars.
