Answer 2

Problem Analysis

We are given the following information: - There were a total of 480 people at the celebration. - The number of women was 40 more than the number of men. - The number of adults was 40 more than the number of children.

We need to determine the number of men at the celebration.

Solution

Let's assume the number of men at the celebration is x.

According to the given information, the number of women is 40 more than the number of men. Therefore, the number of women can be expressed as x + 40.

Similarly, the number of adults is 40 more than the number of children. Therefore, the number of adults can be expressed as x + 40.

Since the total number of people at the celebration is 480, we can write the equation:

x + (x + 40) + (x + 40) + x = 480

Simplifying the equation:

4x + 120 = 480

Subtracting 120 from both sides:

4x = 360

Dividing both sides by 4:

x = 90

Therefore, there were 90 men at the celebration.

Answer

There were 90 men at the celebration.
