Answer: 6931
Explanation:
79% of all students are taking math this semesters. So there is an additional 21% of students not taking math.
5476/x = 79/100
cross multiply and divide to get the total number of students.
5476 x 100 = 547600
547600 divided by 79 = 6931
check 5476 divided by 6931 = 79%
Further proof of correct answer:
21% of 6931 = 1455
1455 + 5476 equals 6931, so the answer calculated is correct.
