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