A community college has 2,000 students and 50 instructors. Next year, the enrollment will be 6,000. How many new instructors should be hired if the college wants to keep the same student-to-instructor ratio?
Answer (2)
2 , 000 6 , 000 − − 50 x 2 , 000 x = 50 × 6 , 000 / : 2 , 000 x = 2 , 000 300 , 000 x = 150 150 − 50 = 100 A n s w er : 100 n e w in s t r u c t ors .
To maintain the current student-to-instructor ratio of 40 students per instructor, the college needs a total of 150 instructors for 6,000 students next year. Since they currently have 50 instructors, they will need to hire 100 new instructors. Therefore, the college should hire 100 new instructors.
