In a school with 323 students there are 15 more girls than boys.How many boys are there?
b = numer of boys
g = number of girls
There are 15 more girls than boys.
g = b + 15
b + g = 323
b + b + 15 = 323
2 b + 15 = 323 Subtract 15 to both sides
2 b + 15 - 15 = 323 - 15
2 b = 308 Divide both sides by 2
2 b / 2 = 308 / 2
b = 154
154

To find out how many boys are in the school, we need to determine the number of girls and then calculate the number of boys.
Let's assume the number of boys in the school is "x".
According to the given information, there are 15 more girls than boys. So, the number of girls would be "x + 15".
The total number of students in the school is given as 323. Therefore, we can write an equation based on the information given:
x (number of boys) + (x + 15) (number of girls) = 323
Now, we can solve this equation to find the value of "x" (number of boys):
x + x + 15 = 323
2x + 15 = 323
2x = 323 - 15
2x = 308
x = 308 / 2
x = 154
So, there are 154 boys in the school.
