Question

A high school graduating class is made up of 505 students. There 175 more girls than boys. How many boys are in the class

Answer 1

165 boys are in the classroom

Answer 2

165

Explanation:

let the number of boys be x and girls be y.

But there are 175 more girls than boys, so y = x + 175

sum of boys and girls is 505

x + y = 505

and y = x + 175

x + x + 175 = 505

2x = 330

x = 165
