Write the equation and solve the problem:
A high school graduating class is made up of 512 students. There are 70 more girls than boys. How many boys are in the class?
Let x = number of boys
x + x + 70 = 512
2x = 512 - 70
2x = 442
x = ?
x=221
Thanks Ms. Sue you are the best!
You're welcome, Clair.
To solve this problem, let's set up an equation.
Let's assume the number of boys in the class is "x".
According to the given information, the number of girls is 70 more than the number of boys. So, the number of girls can be represented as "x + 70".
Since the total number of students in the class is 512, we can write the equation:
x (number of boys) + (x + 70) (number of girls) = 512
Now, let's solve the equation to find the value of "x" (number of boys).
x + x + 70 = 512
2x + 70 = 512
2x = 512 - 70
2x = 442
x = 442 / 2
x = 221
Therefore, there are 221 boys in the class.
