Final answer:
Taylor's net proceeds from the stock transaction are $525, after accounting for the initial purchase cost and broker's commissions on both the buying and selling of the stock.
Step-by-step explanation:
Taylor bought 200 shares of stock at $18.12 per share and paid a flat brokerage fee of $30. To find the initial cost, we multiply the number of shares by the purchase price and then add the fee:
200 shares × $18.12/share + $30 = $3,654
When Taylor sold his shares at $21 per share, his gross proceeds were:
200 shares × $21/share = $4,200
The broker commission of 0.5% on the selling price is calculated as:
$4,200 × 0.005 = $21
To find Taylor's net proceeds, we subtract both the initial cost and the selling commission from the gross proceeds:
$4,200 - $3,654 - $21 = $525
Therefore, Taylor's net proceeds from the stock transaction are $525.
