conversations.value: Marissa's sunflower is  21 inches taller than her little sister. If her sister is 4 feet 3 inches tall, how tall is Marissa's sunflower in feet?

conversations.value: Since 1 foot is equal to 12 inches, then 4 feet is equal to 4 x 12 = 48 inches.
  So, Marissa's sister is 48 + 3 = 51 inches tall.
  The sunflower is 51 + 21 = 72 inches tall.
  Therefore, the sunflower is 72/12 = 6 feet tall.
