conversations.value: First find the total number of trips Janet takes during the week: 2 trips/day * 5 days/week = 10 trips/week
  Then multiply this number by the cost per trip to find her current weekly spending: 10 trips/week * $2.20/trip = $22/week
  Then subtract the cost of the weekly bus pass from this number to find her savings: $22/week - $20/week = $2
