Answer: 
 -$560
Explanation: 
The computation of capital gain on this investment is shown below:- 
Capital gain = (Stock price - Paid shares) × Sold shares 
where, 
The Stock price is $30.92
Paid shares is $32.04
And, the sold shares is 500 shares
Now placing these values to the above formula
So, the capital gain on this investment is 
= ($30.92 - $32.04) × 500 
= -$1.12 × 500 
= -$560
