Final answer:
To calculate the capital gains on this investment, subtract the purchase price from the selling price to find a capital loss of $6.72.
Step-by-step explanation:
To calculate the capital gains on this investment, we need to subtract the purchase price from the selling price. In this case, the purchase price is $63.51 and the selling price is $56.79. Therefore, the capital gains can be calculated as:
Capital gains = Selling price - Purchase price
= $56.79 - $63.51
= -$6.72
Since the result is negative, it means that there is a capital loss of $6.72 on this investment.
