To find the total enrollment in the university, we can use the information given: 3% of the students come from a certain state, and there are 156 students from that state.
Let \( x \) be the total enrollment of the university. According to the information given:
\[ 0.03x = 156 \]
To find \( x \), we can divide both sides of the equation by 0.03:
\[ x = \frac{156}{0.03} \]
Calculating the right-hand side:
\[ x = 156 \div 0.03 = 5200 \]
Therefore, the total enrollment in the university is 5200 students.
