Answer :
We start with the total number of students in the school, [tex]$764$[/tex], and the fact that [tex]$118$[/tex] of those students are in third grade. Let [tex]$s$[/tex] represent the number of students in all of the other grades. Since the total number of students is the sum of the third grade students and the students in the other grades, we can write the equation as:
[tex]$$
118 + s = 764.
$$[/tex]
This equation shows that if you add the [tex]$118$[/tex] third grade students to the [tex]$s$[/tex] students from the other grades, the total is [tex]$764$[/tex]. Thus, the correct option is the equation
[tex]$$
118 + s = 764.
$$[/tex]
[tex]$$
118 + s = 764.
$$[/tex]
This equation shows that if you add the [tex]$118$[/tex] third grade students to the [tex]$s$[/tex] students from the other grades, the total is [tex]$764$[/tex]. Thus, the correct option is the equation
[tex]$$
118 + s = 764.
