The ratio of the students to the professors is 1200:80 = 30:2 = 15.
- After enrollment the number of students will be 1450.
- So the number of professors after enrollment will become the unknown number, x.

➡️ 1200/80 = 1450/x

➡️ 1200x = 1450 * 80

➡️ 1200x = 116,000

➡️ x = 116,000/1200

➡️ x= 96.67
