<human>:  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?
<bot>: How much did the jeans cost in total? ** The total spent on both pairs of jeans was $110 - $40 - $30 = $<<110-40-30=40>>40.
How much did one pair of jeans cost? ** One pair of jeans would cost $40 / 2 = $<<40/2=20>>20.
