Question

Students enrolled in honors math increased by 12% this year. If s represents students, then an expression to represent this is 1.12s

Answer 1

Given that s represents the number of students enrolled in maths honors, a 12% increase in the number of students implies that

$\frac{12}{100}\times s=0.12s\text{ }$

This means that the number of students increased by 0.12s.

Thus, the total number of students enrolled in honors math will be

$\begin{gathered} \text{initial number of students + additional number of student} \\ \text{thus, we have} \\ s+0.12s=1.12s \end{gathered}$

Thus, 1.12s represents the expression for the total number of students
