conversations.value: Since Will was 4 years old 3 years ago, then he is 4+3 = 7 years old now
  Dina is twice as old as he is so she is 2*7 = 14 years old now
  In 5 years, Will will be 7+5 = 12 years old
  In 5 years, Diane will be 14+5 = 19 years old
  The sum of their ages at that time will be 12+19 = 31 years
