The present ratio of students to teachers at a certain school is 30 to 1. If the student enrollment were to increase by 50 students and the number of teachers were to increase by 5, the ratio of students to teachers would then be 25 to 1. What is the present number of teachers ?

Write out what you are given!!

Let Students = S
Let Teachers = T

S/T = 30

(S+50)/(T+5) = 25

combine these two formulas to get T=15
