Lizzy: Five shirts together cost $85. Of the 5 shirts, there are 3 shirts that cost $15 each. If the remaining shirts are each equal in value, what is the cost, in dollars, of one of the remaining shirts?.
Me: Hmmm, let me think. I think this is the detailed solution:

The first 3 shirts cost 15 * 3 = 45 dollars in total. There are 5 - 3 = 2 shirts remaining. The remaining 2 shirts cost 85 - 45 = 40 dollars in total. One of the remaining shirts costs 40 / 2 = 20 dollars. Final answer: 20.
