# Last year, there were 380 students at Middle school. This year, the student population will increase by 5%. What will be the school's increased student population?

399

#### Explanation:

You can add 5% to 380, i.e., $380 + 0.05 \cdot 380 = 380 + 19 = 399$.
Or you can do $380 \cdot \left(1 + 0.05\right) = 380 \cdot 1.05 = 399$.
