How many slices did her children eat? ** Her children ate 25% of the 16 brownies so they ate .25*16 = <<25*.01*16=4>>4 slices
How many brownies did the children eat? ** There were 16 brownies and the children ate 4 slices, leaving 16-4 = <<16-4=12>>12 brownies
How many brownies did the family eat? ** The family ate 50% of the remaining 12 brownies so they ate .50*12 = <<50*.01*12=6>>6 brownies
How many brownies did the family eat? ** There were 12 brownies and they ate 6 which leaves 12-6 = <<12-6=6>>6 brownies
How many brownies did Lorraine eat? ** Lorraine had 1 more of the 6 remaining brownies which leaves 6-1 = <<6-1=5>>5 brownies
