Based on the image you provided, the task is to write spreadsheet formulas for certain cells related to a frequency distribution table for room prices on a travel package.

### Explanation of Formulas:

#### a. **C9 (Total number of rooms):**
The total number of rooms is the sum of all the room frequencies from C2 to C8. In Excel, the formula would be:
```
=SUM(C2:C8)
```

#### b. **D3 (Relative Frequency for Row 3 - Premium Standard):**
The relative frequency is the frequency of rooms (from column C) divided by the total number of rooms (which is in cell C9). In Excel, the formula would be:
```
=C3/$C$9
```

#### c. **D7 (Relative Frequency for Row 7 - Premium Luxury):**
Similar to D3, this is the relative frequency for Premium Luxury, calculated by dividing the number of Premium Luxury rooms by the total number of rooms:
```
=C7/$C$9
```

#### d. **E4 (Cumulative Frequency for Row 4 - Deluxe):**
Cumulative frequency adds up the frequencies from the previous rows. For Deluxe, it is the sum of frequencies for the first three room categories:
```
=E3 + C4
```

#### e. **F5 (Relative Cumulative Frequency for Row 5 - Premium Deluxe):**
The relative cumulative frequency is the cumulative frequency of Premium Deluxe rooms (from E5) divided by the total number of rooms (C9). The formula would be:
```
=E5/$C$9
```

Would you like a further breakdown of any specific formula, or do you have any questions?

### Follow-up questions:
1. How do cumulative frequencies help in understanding data distribution?
2. What is the importance of relative frequency in data analysis?
3. Why is the total number of rooms used as a denominator in calculating relative frequency?
4. What role does absolute frequency play in comparison to relative frequency?
5. Can the formulas be modified if there are more rows or categories added to the table?

#### Tip:
In Excel, always use absolute references (with `$`) when referring to totals to prevent changes during copying of formulas.

Write the spreadsheet formulas for the indicated cells in the room frequency distribution table, including total rooms, relative frequency, cumulative frequency, and relative cumulative frequency.

Learn how to calculate total rooms, relative frequency, cumulative frequency, and relative cumulative frequency in a room pricing distribution table using Excel. This example walks through the process using basic spreadsheet functions like SUM and relative referencing, ideal for Grades 11-12 or college students.
