conversations.value: To get ready for the new school year, Mary brought her two kids shopping. She bought her son James, a coat for $40 and two pairs of jeans. She bought his sister Jamie, a pair of shoes for $30. The total cost of the items was $110. If the two pairs of jeans for James cost the same price, how much did one pair of jeans cost?
  How to solve this?

conversations.value: The total spent on both pairs of jeans was $110 - $40 - $30 = $40.
  One pair of jeans would cost $40 / 2 = $20.
