conversations.value: After one year, Sam had $10,000 * 1.2 = $12,000.
  After two years, he had $12,000 * 1.2 = $14,400.
  After the third year, he had $14,400 * 1.2 = $17,280.
  He then invested more money until he had 3 * $17,280 = $51,840.
  The first year after that, he had $51,840 * 1.15 = $59,616.
