Rebecca bought 2 pies for the holiday weekend. Each pie was sliced into 8 slices. Rebecca ate 1 slice of each pie. Her family and friends ate 50% of the remaining pies over the weekend. On Sunday evening Rebecca and her husband each had another slice of pie. How many slices are remaining?

She bought 2 pies that had 8 slices each for a total of 2 * 8 = 16 slices. Rebecca ate 2 of the 16 slices leaving 16 - 2 = 14 slices. Her family and friends at 50% of the pie so they ate 14 * .50 = 7 slices. There were 14 slices and her family and friends ate 7 slices so that leaves 14 - 7 = 7 slices. Sunday night Rebecca and her husband each had a slice from the remaining slices so that leaves 7 - 2 = 5 slices.
Thus, the answer is 5.
