Answer 1

To calculate the total cost for each number of seed packets ordered, we can use the formula:

\[
\text{Total Cost} = (\text{Number of packets} \times \text{Cost per packet}) + \text{Shipping fee}
\]
where the cost per packet is $2.25 and the shipping fee is $4.50.

### Part 1: Complete the Table

1. **Total Cost: $11.25**
\[
\text{Total Cost} = (n \times 2.25) + 4.50 = 11.25
\]
\[
n \times 2.25 = 11.25 - 4.50 = 6.75
\]
\[
n = \frac{6.75}{2.25} = 3
\]
Number of Seed Packets Ordered: **3**

2. **Total Cost: $15.75**
\[
\text{Total Cost} = (n \times 2.25) + 4.50 = 15.75
\]
\[
n \times 2.25 = 15.75 - 4.50 = 11.25
\]
\[
n = \frac{11.25}{2.25} = 5
\]
Number of Seed Packets Ordered: **5**

3. **Total Cost: $18.00**
\[
\text{Total Cost} = (n \times 2.25) + 4.50 = 18.00
\]
\[
n \times 2.25 = 18.00 - 4.50 = 13.50
\]
\[
n = \frac{13.50}{2.25} = 6
\]
Number of Seed Packets Ordered: **6**

4. **Total Cost: $27.00**
\[
\text{Total Cost} = (n \times 2.25) + 4.50 = 27.00
\]
\[
n \times 2.25 = 27.00 - 4.50 = 22.50
\]
\[
n = \frac{22.50}{2.25} = 10
\]
Number of Seed Packets Ordered: **10**

### Summary of the Table

- **Number of Seed Packets Ordered**:
- 3 → Total Cost: $11.25
- 5 → Total Cost: $15.75
- 6 → Total Cost: $18.00
- 10 → Total Cost: $27.00

Thus, the completed table is as follows:

| Number of Seed Packets Ordered | Total Cost, Including Shipping ($) |
|--------------------------------|------------------------------------|
| 3 | $11.25 |
| 5 | $15.75 |
| 6 | $18.00 |
