Answer:
7 rows.
Explanation:
We have been given that a theater manager needs to set up 54 chairs for a show. Each row can hold up to 8 chairs.
To find number of rows, we will divide total number of chairs by number of chairs that each row can hold.
![\text{Number of rows}=(54)/(8)](https://img.qammunity.org/2021/formulas/mathematics/high-school/idlg4ik4pz5cykwp9kyjajfkxjnjehuc2l.png)
![\text{Number of rows}=6.75](https://img.qammunity.org/2021/formulas/mathematics/high-school/y8xgo6vvlmtsepizjz7tj9dtz60sv04av3.png)
![\text{Number of rows}\approx 7](https://img.qammunity.org/2021/formulas/mathematics/high-school/k9r4elu13lccysyj5461ajriz37iwa2kzd.png)
Therefore, the manager will set up 7 rows.
