Let's address each point step by step:

1. The function rule for the amount of seats in the reserved section can be defined as follows:

\( f(n, m) = n \times m \)

where \( n \) is the number of rows and \( m \) is the number of seats per row.

For the reserved seating section, that is:

\( f_{\text{reserved}}(n, m) = 10 \times 12 \)

2. The revenue of the reserved section can be calculated by multiplying the number of seats in the reserved section by the price per seat:

\( \text{Revenue}_{\text{reserved}} = f_{\text{reserved}}(n, m) \times \text{Price per seat} \)

\( \text{Revenue}_{\text{reserved}} = 10 \times 12 \times 25 \)

3. The function rule for the amount of seats in the general section can be defined similarly to the reserved section:

\( f_{\text{general}}(n, m) = 30 \times 16 \)

4. The revenue of the general section can be found by multiplying the number of seats in the general section by the price per seat:

\( \text{Revenue}_{\text{general}} = f_{\text{general}}(n, m) \times \text{Price per seat} \)

\( \text{Revenue}_{\text{general}} = 30 \times 16 \times 10 \)

5. The total revenue of the building is the sum of the revenues from both sections:

\( \text{Total Revenue} = \text{Revenue}_{\text{reserved}} + \text{Revenue}_{\text{general}} \)

6. To represent the revenue from the reserved section and an unknown amount of tickets from the general section, we can use a function where \( g \) stands for the number of general section tickets sold. Since the revenue from the reserved section is fixed (all tickets have been sold), we only need to consider the variable component for the general section:

\( r(g) = \text{Revenue}_{\text{reserved}} + (g \times \text{Price per general seat}) \)

Let's calculate the actual values for points 2, 4, 5, and the function rule for point 6:

2. Revenue of the reserved section:
\( \text{Revenue}_{\text{reserved}} = 10 \times 12 \times 25 = 3000 \) dollars

4. Revenue of the general section (assuming all seats are sold):
\( \text{Revenue}_{\text{general}} = 30 \times 16 \times 10 = 4800 \) dollars

5. Total revenue (assuming all seats are sold in both sections):
\( \text{Total Revenue} = 3000 + 4800 = 7800 \) dollars

6. Function rule for the revenue from the reserved section and an unknown number of general section tickets:
\( r(g) = 3000 + (g \times 10) \)

where \( r \) is the total possible revenue and \( g \) stands for the number of general section tickets sold.
5. What is the total revenue of the building?
To calculate the total revenue of the building, we add up the revenues from both the reserved and the general sections. Let's calculate them first:

Reserved Section Revenue:
\( \text{Revenue}_{\text{reserved}} = \text{Price per reserved seat} \times \text{Number of reserved seats} \)
\( \text{Revenue}_{\text{reserved}} = \$25.00 \times (10 \text{ rows} \times 12 \text{ seats per row}) \)
\( \text{Revenue}_{\text{reserved}} = \$25.00 \times 120 \)
\( \text{Revenue}_{\text{reserved}} = \$3,000 \)

General Section Revenue (if all seats are sold):
\( \text{Revenue}_{\text{general}} = \text{Price per general seat} \times \text{Number of general seats} \)
\( \text{Revenue}_{\text{general}} = \$10.00 \times (30 \text{ rows} \times 16 \text{ seats per row}) \)
\( \text{Revenue}_{\text{general}} = \$10.00 \times 480 \)
\( \text{Revenue}_{\text{general}} = \$4,800 \)

Total Revenue (with all seats sold in both sections):
\( \text{Total Revenue} = \text{Revenue}_{\text{reserved}} + \text{Revenue}_{\text{general}} \)
\( \text{Total Revenue} = \$3,000 + \$4,800 \)
\( \text{Total Revenue} = \$7,800 \)

Therefore, the total revenue of the building with all seats sold is \$7,800.
Use g as the variable for number of general section

tickets and use r for the possible revenue.
To represent the possible revenue including all of the reserved section tickets and a variable number of general section tickets, we can use the following function rule:

\( r(g) = \text{Revenue from all reserved section tickets} + (\text{Price per general seat} \times g) \)

In this case, we already know that all of the reserved section tickets have been sold, providing a fixed revenue. Let's denote the fixed revenue from the reserved section tickets as \( R_{reserved} \). Let's use \( P_{general} \) as the price per general section ticket.

Now we express \( r \) as a function of \( g \):

\( R_{reserved} = \text{Revenue from all reserved section tickets} \)
\( R_{reserved} = 10 \text{ rows} \times 12 \text{ seats per row} \times \$25 \text{ per seat} \)
\( R_{reserved} = 120 \text{ seats} \times \$25 \text{ per seat} \)
\( R_{reserved} = \$3,000 \)

\( P_{general} = \text{Price per general seat} \)
\( P_{general} = \$10 \)

Therefore, the function for \( r \) given a number of general section tickets \( g \) sold is:

\( r(g) = R_{reserved} + (P_{general} \times g) \)
\( r(g) = \$3,000 + (\$10 \times g) \)

This function rule gives us the possible revenue (represented by \( r \)) for any number of general section tickets sold (represented by \( g \)).
