Answer 1

Since it says "about", you need to round. If you round 4,358 it can be like 4,500. Then, you can multiply 4,500 x 3, which equals 13,500. So your answer would be Jefferson High School has ABOUT 13,500 students. 

Answer 2

Jefferson High School has 13074 students because 4,359 * 3 is 13074.
