To find out how much each share is worth after a 10% increase, you first need to determine the value of each share initially.
You invested $2,500 in total and bought 125 shares. To find the initial value of each share, you can calculate it as follows:
\[ \text{Initial value per share} = \frac{\text{Total investment}}{\text{Number of shares}} = \frac{2500}{125} = 20 \]
So, each share is initially worth $20.
Next, you need to calculate the new value of each share after a 10% increase:
\[ \text{Increase} = \text{Initial value per share} \times 0.10 = 20 \times 0.10 = 2 \]
Now, add the increase to the initial value to find the new value:
\[ \text{New value per share} = \text{Initial value per share} + \text{Increase} = 20 + 2 = 22 \]
Thus, after the 10% increase, each share is worth $22.00.
