Explanation:
Given:
Number of rows in theater = n
Number of seats in each row = m
Total number of seats in the theater = Number of rows in theater
Number of seats in each row=
![m * n](https://img.qammunity.org/2020/formulas/mathematics/middle-school/btyi4erdxxbl8hez7s3sgh63gx4pt2x0ze.png)
Now given each ticket costs =
![\$5.60](https://img.qammunity.org/2020/formulas/mathematics/middle-school/2hi2qi8e618dkg8pztzrx3nix04qb7x2mm.png)
So to find total of all tickets we need multiply each ticket cost by Total number of seats in the theater
Total tickets cost = each ticket cost
Total number of seats in the theater =
![\$5.60 * m * n](https://img.qammunity.org/2020/formulas/mathematics/middle-school/n65nbikhuybqyua0bozp92czd67ito0wju.png)
