Answer:

25%

Step-by-step explanation:

The percent of increase can be calculated using following formula:

[tex]\text{Percent Increase}=\dfrac{\text{Final Amount-Initial Amount}}{\text{Initial Amount}}\cdot 100\%.[/tex]

In your case,

  • Initial amount = 12 students;
  • Final amount = 15 students,

then

[tex]\text{Percent Increase}=\dfrac{15-12}{12}\cdot 100\%=\dfrac{3}{12}\cdot 100\%=\dfrac{1}{4}\cdot 100\%=25\%.[/tex]
