Final answer:
The question does not provide sufficient information to determine the difference in overall loss or gain between selling at a high or low price. Therefore, the correct answer is 'None of the above'.
Step-by-step explanation:
In order to determine the difference in overall loss or gain between selling at the current day's high price or low price, we first need to calculate the total investment made by the investor. The investor purchased 115 shares of Stock A at $390 per share and 30 shares of Stock B at $145 per share. To calculate the total investment, we multiply the number of shares bought by the price per share for both Stock A and Stock B:
- Stock A: 115 shares * $390/share = $44,850
- Stock B: 30 shares * $145/share = $4,350
The total amount invested would be the sum of these two investments:
Total investment = $44,850 (Stock A) + $4,350 (Stock B) = $49,200
The question does not provide the current day's high and low selling prices for Stock A and Stock B, therefore we are unable to calculate the difference in loss or gain. Without this information, the correct answer cannot be determined from the options provided. Hence, the answer is d. None of the above.
