conversations.value: Tiffany is going to the beach and wants to make sure she has enough sunscreen. She knows she needs to re-apply sunscreen after 2 hours. She also knows she needs 3 ounces of sunscreen each application and a bottle contain 12 ounces and costs $3.5. If she is there for 16 hours, how much will the sunscreen cost?
  Give me a solution to this problem

conversations.value: She needs to apply sunscreen 8 times because 16 / 2 = 8
  She will use 24 ounces of sunscreen because 3 x 8 = 24
  This will take 2 bottles because 24 / 12 = 2
  This will cost $7 because 2 x 3.5 = 7
