To compute the total return on the investment, we use the formula:

$\text{Total Return} = \frac{\text{Ending Value} - \text{Beginning Value}}{\text{Beginning Value}} \times 100$

Step 1: Find the beginning and ending values.

• Beginning Value: The initial purchase cost is 100 shares at $70 per share. $\text{Beginning Value} = 100 \times 70 = 7000$
• Ending Value: You sell the stock for $9,800.

Step 2: Compute the total return.

$\text{Total Return} = \frac{9800 - 7000}{7000} \times 100 = \frac{2800}{7000} \times 100 = 40\%$

So, the total return is 40%.
