NNADVOKAT [17]

Answer:

Jacob's rate of return is <u>19.2%</u>.

Step-by-step explanation:

Given:

Jacob invested $500 in a stock and after a year had $596.

Now, to find the rate of return.

So, we get the amount of return first:

Present value - value before a year = Return.

$596 - $500 = $96.

Now, to get the rate:

Return / Value before a year × 100.

=\frac{96}{500}\times 100

=\frac{9600}{500}

=\ 19.2\%.

Therefore, Jacob's rate of return is 19.2%.
