To determine the original worth of the shares, we can use the concept of profit as a percentage of the original value. Since the profit is 25% of the original value, we can set up the following equation:
Profit = Original Value x Percentage
1328 = Original Value x 0.25
To solve for the Original Value, we can divide both sides of the equation by 0.25:
Original Value = 1328 / 0.25
Original Value = 5312
Therefore, the shares were worth $5312 when she originally purchased them.
