You buy 50 shares of a stock on October 1 @ $72.30 per share. You sold those same shares on December 15 for $83.13 per share. What was your percentage gained on the transaction, ignoring fees and commissions?

To determine the percentage gained on the transaction, you first need to calculate the total cost of the shares and the total revenue from selling them.

1. Initial Purchase Cost: The cost per share is $72.30, and you bought 50 shares. Therefore, your initial investment is calculated as:

[

\text{Total Cost} = \text{Number of Shares} \times \text{Cost Per Share} = 50 \times 72.30 = 3,615

]

2. Selling Revenue: When you sell the shares at $83.13 per share, the total revenue from the sale is:

[

\text{Total Revenue} = \text{Number of Shares} \times \text{Selling Price Per Share} = 50 \times 83.13 = 4,156.50

]

3. Calculating Gain: Your gain from the transaction is the difference between the selling revenue and the initial cost:

[

\text{Gain} = \text{Total Revenue} - \text{Total Cost} = 4,156.50 - 3,615 = 541.50
