Answer 2

Problem Analysis

To solve this problem, we need to determine the number of girls who went to the theater, given that there were 36 first graders, 42 second graders, and a total of 38 boys among them.

Solution

Let's assume the number of girls who went to the theater is represented by the variable G.

We know that the total number of first graders is 36, and the total number of second graders is 42. Therefore, the total number of students who went to the theater is 36 + 42 = 78.

We also know that the total number of boys who went to the theater is 38.

To find the number of girls, we can subtract the number of boys from the total number of students: G = Total number of students - Number of boys

Substituting the values we have: G = 78 - 38

Now we can calculate the number of girls who went to the theater.

Calculation

G = 78 - 38 = 40

Therefore, 40 girls went to the theater.

Answer

The number of girls who went to the theater is 40.
