Let's add the positive numbers first:
$4,000 + $9,000 + $6,000 + $10,000 = $29,000 in earnings
Now let's calculate the negative numbers:
-$3,000 + -$2,000 = -$5,000
Next, subtract $5,000 from $29,000 to gain $24,000.
Lastly, divide $24,000 by 6 given that that's the full number of investments. In this instance, you are earning a mean or average of $4,000 per investment.
