Kyra observed that 85% of the students at a library liked reading mystery stories. If 30 students at the library did not like reading mystery stories, the number of students at the library who liked mystery stories was _____.
If 85% of the students liked mysteries, then what percentage of them did NOT like mysteries? Let x be the number of students at the library. Using the fact that 30 students did not like reading mysteries, can you now find the total number of students at the library, x?
so if there are 200 students in the library minus the 30 student that don't like mysteries. 170 students are left in these are the students that like mystery books right.
Mind showing (or at least discussing) how you decided that x = 200 (students)? Hope your answer was obtained algebraically.
