The table in the image represents a proportional relationship between the number of pounds of bananas purchased and the total cost in dollars. The given data points are:

- 3 pounds → $1.47
- 5 pounds → $2.45
- 9 pounds → $4.41

We are asked to determine the missing row, which includes both the number of pounds and the total cost.

### Step 1: Determine the Unit Rate
To find the cost per pound of bananas, we can calculate the unit rate using any of the given pairs. For example:

\[
\text{Unit rate} = \frac{\text{Total cost}}{\text{Number of pounds}} = \frac{1.47}{3} \approx 0.49
\]

Similarly, for 5 pounds:

\[
\text{Unit rate} = \frac{2.45}{5} = 0.49
\]

And for 9 pounds:

\[
\text{Unit rate} = \frac{4.41}{9} \approx 0.49
\]

The unit rate (cost per pound) is consistent across the given data, which is approximately $0.49 per pound.

### Step 2: Determine the Missing Values
To find the missing values in the table, we can use the unit rate. Let's consider the cost for different possible numbers of pounds:

- **4 pounds**: 
  \[
  4 \times 0.49 = 1.96
  \]
- **7 pounds**: 
  \[
  7 \times 0.49 = 3.43
  \]
- **8 pounds**: 
  \[
  8 \times 0.49 = 3.92
  \]

Thus, a possible pair for the missing row could be:
- **7 pounds → $3.43** or **4 pounds → $1.96** or **8 pounds → $3.92**.

### Final Answer
Given the options calculated, the missing row could potentially be either:

- **7 pounds → $3.43**
- **4 pounds → $1.96**
- **8 pounds → $3.92**

If the table requires a round number of pounds that lies between the given values, **7 pounds → $3.43** is the most likely candidate.
