conversations.value: Keaton can harvest his oranges every year is 12/2=6 times.
  So the total money he earns for his oranges every year is $50 x 6 = 300.
  He can harvest his apples 12/3= 4 times in a year.
  So the total money he earns for the apple in a year is $30 x 4 = 120.
  Therefore, the total money he earns for his oranges and apples is $300 + $120 = $420.
