Answer:
Let's assume the number of adults attending the performance is represented by 'x', and the number of children attending is represented by 'y'.
According to the given information, the entrance fee for adults is R50 each, and for children is R20 each.
The total amount raised by the school is R31,400. We can write an equation based on the total amount raised:
50x + 20y = 31,400
This equation represents the total value of the entrance fees paid by adults and children.
To solve this equation, we need another equation to relate the variables 'x' and 'y'.
Since we don't have any other information about the number of adults or children, we cannot determine their relationship based on the given information. Therefore, we cannot find a unique solution for 'x' and 'y' unless there is additional information provided.
If there is additional information or if you have any specific values for 'x' or 'y', I can assist you in solving the equation and finding the number of adults and children attending the performance.
