Question

In a grade with 164 students,there were 18 more girls than boys. How many girls were in the grade?

Answer 1

There were 91 girls.

Explanation:

164 students - 18 students = 146 students

146 students divided by 2 genders = 73 students

73 students + 18 girls = 91

Answer 2

91

Explanation:

Let us set boys as x. Girls would then be x+18

Girls and Boys together would be x + x+ 18

Therefore,

x+x+18=164

2x+18=164

2x=146

x=73

Since girls are x + 18, they would be 73 + 18, or 91.

I hope this helps! :)
