Brandon received a book for his birthday and read seventy-six pages in 4 hours. Later, he read eighty-five pages in 5 hours. Does his reading follow a direction variation? Explain
76 / 4 = 19 pp/hr
85 / 5 = 17 pp/hr
If not a direct variation. If he'd read 95 pages in 5 hours, then it would have been direct.
