She cut each pie into 8 pieces and set the five pies out on the buffet table for the guests to serve themselves.  At the end of the evening, after the guests had taken and eaten their pieces of pie, there were 14 pieces of pie remaining.  How many pieces were taken by the guests?

conversations.value: To start the evening, there were 5 pies, each with 8 pieces, which is 5*8=40 pieces of pie.
  If only 14 remained, then 40-14=26 pieces of pie had been taken by guests.
