Now, to get the percentage of occupancy of the theatre last Friday.
Let
be all the seats in the stalls.
Total number of seats in the circle occupied by audience last friday = 528.
According to question, 2 : 5 is the ratio in the number of seats in the circle compared to the number of seats in the stalls.
So, 2 is equivalent to 5.
And, 528 is equivalent to
.
Now, to get the number of stalls by using cross multiplication method:
![(2)/(5) =(528)/(x)](https://img.qammunity.org/2021/formulas/mathematics/high-school/1r0fxztxanms4874bz73wp3ic73vlz4a1d.png)
By cross multiplying we get:
![2x=2640](https://img.qammunity.org/2021/formulas/mathematics/high-school/zqpvzkrn9jt92y473gsa5noqgk9fjv917v.png)
Dividing both sides by 2 we get:
![x=1320.](https://img.qammunity.org/2021/formulas/mathematics/high-school/8sn564z1k3hr11dixbxg2ajjwrws3nkbpt.png)
Total number of seats in the stalls = 1320.
Now, to get the people occupied seats in the stalls on last friday:
![(2)/(3) \ of\ 1320\\\\=(2)/(3) * 1320\\\\=880.](https://img.qammunity.org/2021/formulas/mathematics/high-school/8tjp5ywzix0q93o3hf3imo45lj1a4v8sw2.png)
Thus, people occupied 880 seats in the stalls on last friday.
So, the total number of seats in the circle and stalls:
![1320+528\\\\=1848.](https://img.qammunity.org/2021/formulas/mathematics/high-school/oni1vggl9kuhciob5mltuwdasyqssepb3m.png)
And, the total number of seats people occupied last friday:
![528+880\\\\=1408.](https://img.qammunity.org/2021/formulas/mathematics/high-school/lpx81ghufd9e9xacyompbvcojqg1ibvwef.png)
Now, to get the percentage of occupancy of the theatre last Friday:
![(1408)/(1848) * 100](https://img.qammunity.org/2021/formulas/mathematics/high-school/1b6xttcukbmacvqvagvrujln7tztx7gij2.png)
![=(140800)/(1848) \\\\=76.19\%.](https://img.qammunity.org/2021/formulas/mathematics/high-school/717t2djh8gqzjw9br1kj71tonruqz4byud.png)
Therefore, 76.19% the percentage of occupancy on last Friday.
