Final answer:
After the stock increased by $62 from its original $195 per share to $257 per share, Tom sold his stock as it exceeded his target sale price of $25 per share. The answer is a) Yes, he sold his stock.
Step-by-step explanation:
The student asked: Tom planned to sell his stock when it reached $25 per share. In the morning, the stock was $195 per share. It went up $62 by the afternoon. Did he sell his stock? To answer this question, we need to calculate the stock's value after the increase. In the morning, the stock was at $195. It increased by $62, so in the afternoon, the stock's value was $195 + $62 = $257 per share.
Since Tom planned to sell his stock when it reached $25 per share, and the stock's value in the afternoon went well beyond that, at $257 per share, we can safely say that Tom did sell his stock.
Therefore, the correct answer to the question is: a) Yes, he sold his stock.
