Final answer:
The total return is calculated by subtracting the selling price from the purchase price, dividing by the purchase price, and multiplying by 100. The total return in this scenario is -58.12%.
Step-by-step explanation:
The total return on the investment can be calculated using the initial purchase price and the selling price of the shares. In this case, the original purchase was $12,646 and the shares were sold for $5,306. The change in value is $5,306 - $12,646 = -$7,340.
To find the total percentage return, we divide the change in value by the original purchase price, and then multiply by 100 to get a percentage. So, the total return is ($7,340 / $12,646) × 100 = -58.12%. Therefore, the correct answer is d) -58.12%.
