Answer:

199 a 426 students

Step-by-step explanation:

first to see what amount we are talking about in each case, let's see how many students each percentage represents

22% of students:  (22 * ​​1420 students) /100  = 312.4 students

8% of students: (8*1420 students)/100 = 114.6 students

that is, that the average number of students who work part time is 312.4 students. And that number can vary up to 114.6 students above and up to 114.6 students below

that can be expressed as

22% + 8% = 312.4 + 113.6 = 426 students

and

22% -8% = 312.4-113.6 = 198.8≅ 199 students
