Answer

Explanation:

Step1: Let the number of boys be $x$.

Since there are 7 more girls than boys, the number of girls is $x + 7$.

Step2: Set up an equation based on total students.

The total number of students is 23, so $x+(x + 7)=23$.

Step3: Simplify the equation.

$2x+7 = 23$.

Step4: Solve for $x$.

Subtract 7 from both sides: $2x=23 - 7=16$. Then divide both sides by 2, $x = 8$ (number of boys).

Step5: Find the number of girls.

The number of girls is $x + 7=8 + 7 = 15$.

Answer:

There are 15 girls in the class.
