A community college has 3,000 students and 90 instructors. The college plans that enrollment will be 3,500 next year. How many new instructors should be hired if the college wants to keep the same student to instructor ratio?

3,000 / 90 = 33.33 students per instructor
3,500 / 33.3 = 105.1
105  90 = 15
