conversations.value: Please show me the solution for: Harper drinks a 1/2 bottle of mineral water per day.  She buys the mineral water by the case at a big box store.  They come 24 bottles to a case and are currently on sale for $12.00.  If she wants to buy enough cases to last her 240 days, how much will she spend?

conversations.value: She drinks 1/2 bottle a day and there are 24 bottles in a case so a case will last 24/.5 = 48 days
  She needs enough to last her 240 days and 1 case will last her 48 days so she needs 240/48 = 5 cases
  Each case is on sale for $12.00 and she needs 5 cases so that's 12*5 = $60.00
