Final answer:
To find the number of boys and girls in the chorus, we can set up two equations and solve for the variables. The number of boys is 37, and the number of girls is 26.
Step-by-step explanation:
To solve this problem, let's assign variables to represent the number of boys and girls in the chorus. We can let x be the number of boys and y be the number of girls.
Given that there are 63 students in total, we can write an equation: x + y = 63.
Since there are 11 more boys than girls, we can write another equation: x = y + 11.
Now we can use these two equations to solve for x and y. Let's substitute the value of x from the second equation into the first equation: (y + 11) + y = 63. Simplifying this equation, we get 2y + 11 = 63. Subtracting 11 from both sides, we find that 2y = 52. Dividing both sides by 2, we get y = 26.
Now we can substitute the value of y into the second equation to find x: x = 26 + 11 = 37.
Therefore, there are 37 boys and 26 girls in the chorus.
