conversations.value: I need help with this problem:
  Gary does laundry twice a week. Each load of laundry uses 20 gallons of water, and a gallon of water costs $0.15. How much does Gary spend on water for laundry in a year?
conversations.from: assistant
conversations.value: First multiply the number of times Gary does laundry per week by the number of weeks per year to find how many times he does it in a year: 2 loads/week * 52 weeks/year = 104 loads/year
  Then find how much each load of laundry costs: 20 gallons/load * $0.15/gallon = $3.00/load
  Then multiply the cost of each load by the number of loads to find the total cost: $3.00/load * 104 loads = $312
