The correct Answer is:
To find the net value increase of the two shares held by the stockholder, we can follow these steps: ### Step 1: Identify the changes in value for each company - Company A's share increased by $13. - Company B's share decreased by $8. ### Step 2: Calculate the net change in value To find the net change, we need to consider the increase from Company A and the decrease from Company B. The formula to calculate the net value change is: \[ \text{Net Change} = \text{Increase from Company A} - \text{Decrease from Company B} \] Substituting the values we have: \[ \text{Net Change} = 13 - (-8) \] However, since we are looking for the net increase, we can simplify it to: \[ \text{Net Change} = 13 + 8 \] ### Step 3: Perform the calculation Now, we perform the calculation: \[ \text{Net Change} = 13 + 8 = 21 \] ### Step 4: Determine the net increase Since the value of Company A increased and the value of Company B decreased, we need to find the net increase: \[ \text{Net Increase} = 13 - 8 = 5 \] Thus, the net value of the two shares increased by $5 last month. ### Final Answer The net value of the two shares increased by **$5**. ---
