The librarian at a middle school tallied the books that were checked out in one week. The results are shown in the graph below.
Based on the graph, how many mystery or comic books could you expect to be checked out if a total of 300 books were checked out in a week?
If you add all of the bars you were given it equals 135. so if 300 books were checked out in a week and the bars you added equaled 135, you would subtract it and it would equal 165.
