Answer:

40 total students

Explanation:

Total students: 100%

Let the number of total students be x.

Solving stepwise:

7.5% : 100% --> 3 : x

[tex]\rightarrow \sf \dfrac{7.5}{100} = \dfrac{3}{x}[/tex]

[tex]\rightarrow \sf 7.5x = 3(100)[/tex]

[tex]\rightarrow \sf 7.5x = 300[/tex]

[tex]\rightarrow \sf x =40[/tex]
