Lorraine made a pan of brownies and cut them into 16 pieces.  Her children ate 25% of the brownies when they got home from school.  After dinner,  the entire family ate 50% of the remaining brownies.  After everyone went to bed, Lorraine ate 1 more brownie.  How many brownies are left over?
Her children ate 25% of the 16 brownies so they ate .25*16 = <<25*.01*16=4>>4 slices
There were 16 brownies and the children ate 4 slices, leaving 16-4 = <<16-4=12>>12 brownies
The family ate 50% of the remaining 12 brownies so they ate .50*12 = <<50*.01*12=6>>6 brownies
There were 12 brownies and they ate 6 which leaves 12-6 = <<12-6=6>>6 brownies
Lorraine had 1 more of the 6 remaining brownies which leaves 6-1 = <<6-1=5>>5 brownies
