Calculation of the Number of Children and Adults at the Spectacle

To calculate the number of children and adults at the spectacle, we are given the following information:

- The total number of spectators at the spectacle is 87. - The number of children is 15 more than the number of adults.

Let's denote the number of adults as A and the number of children as C.

From the given information, we can set up the following equations:

1. The total number of spectators: A + C = 87. 2. The number of children is 15 more than the number of adults: C = A + 15.

To solve this system of equations, we can substitute the value of C from equation 2 into equation 1:

A + (A + 15) = 87.

Simplifying the equation:

2A + 15 = 87.

Subtracting 15 from both sides:

2A = 72.

Dividing both sides by 2:

A = 36.

Now that we have the value of A, we can substitute it back into equation 2 to find the value of C:

C = 36 + 15 = 51.

Therefore, there were 51 children and 36 adults at the spectacle.

Answer:

There were 51 children and 36 adults who watched the spectacle.
