conversations.value: She drinks half a container of a 6 serving bottle of iced coffee a day so she drinks 6/2 = 3 servings a day
  There are 7 days in a week and she needs enough bottles to last for 2 weeks so that's 7*2 = 14 days
  She drinks 3 servings a day for 14 days so that's 3*14 = 42 servings
  Each bottle holds 6 servings and she drinks 42 servings in a week so she needs 42/6 = 7 bottles
  The iced coffee is on sale for $3.00 a bottle and she needs 7 bottles for a total of 3*7 = $21.00
