This is incorrect because this is basically saying -10-10=? When is says to add outside of the parentheses and has a negative sign in it you always ignore the addition because it means that you have negative 10 and you are "adding" another negative 10 to it.
You divide each total amount by the number of persons Popcorn: 48/6 = 8 Licorice: 3 X 48 = 144 144/6 = 24 So each person ate 8 ounces of popcorn and 24 inches of licorice laces
