Final answer:
On Saturday, the theatre had a total of 2790 people distributed between adults and children. With 3875 available seats, this meant that 72% of the seats were occupied.
Step-by-step explanation:
To determine the percentage of seats occupied in a theatre, we need to first calculate the total number of children and adults present on a Saturday.
Given that 4/5 of the children are seated in the Stalls and 124 children are in the Circle, we can find out the total number of children. If 124 represents 1/5 of the children, then multiplying 124 by 5 will give us the total number of children:
- 124 children (in the Circle) x 5 = 620 children (total).
Using the ratio of the number of adults to the number of children (7:2), we can determine the number of adults:
- (620 children/2) x 7 = 2170 adults.
If we add the number of adults and children, we get the total number of people in the theatre:
- 620 children + 2170 adults = 2790 people.
Finally, to find the percentage of seats occupied, we divide the total number of people by the total number of seats and then multiply by 100:
- (2790 people / 3875 seats) x 100 = 72%.
Therefore, on that Saturday, 72% of the theatre seats had people sitting on them.
"Your question is incomplete, probably the complete question/missing part is:"
