Gwen received a $900 bonus at work and decided to invest this money in the stock market. She spent one-third of her bonus on stock A, one-third on stock B, and the remaining one-third on stock C.  After one year, stock A and stock B had doubled in value, while stock C had lost half of its value. At the end of the year, how much were Gwen's stocks worth, in dollars? Give me reasons, before answering the question

One - third of her bonus was $900 / 3 = $300. After one year, stock A doubled in value and was worth $300 * 2 = $600. After one year, stock B doubled in value and was worth $300 * 2 = $600. After one year, stock C had lost half its value and was worth $300 / 2 = $150. Altogether, at the end of the year, Gwen's stocks were worth $600 + $600 + $150 = $1350. So the final answer is 1350.
