[Question]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?
[Answer]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. The answer is 1350.

Question: Adam's father deposited $2000 in the bank. It receives 8% interest paid throughout the year, and he withdraws the interest as soon as it is deposited. How much will Adam's father have, including his deposit and the interest received after 2 and a half years?
