conversations.value: Solve the following math problem: 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?

conversations.value: The annual interest is 2000 * 8/100 = $160.
  Interest for two and a half years is 160 * 2.5 = $400.
  So, Adam's father will have 2000 + 400 = $2400 after 2 and a half years.
