Example 8 A Seattle Times article on high school graduation rates reported "The number of schools graduating 60 percent or fewer students in four years - sometimes referred to as "dropout factories" - decreased by 17 during that time period. The number of kids attending schools with such low graduation rates was cut in half." a) Is the "decrease by 17" number a useful comparison? b) Considering the last sentence, can we conclude that the number of "dropout factories" was originally 34?
