We are given the following information:

- The cost of tomatoes is proportional to the number of pounds purchased.
- The table provides the total cost for 7 pounds and 16 pounds of tomatoes.

### Table:

| Pounds of Tomatoes | Total Cost  |
|--------------------|-------------|
| 7                  | $10.43      |
| 16                 | $23.84      |

### Question:
What is the cost for 1 pound of tomatoes?

### Solution:
Since the relationship is proportional, we can calculate the cost per pound by finding the constant of proportionality.

We will use the total cost for each given case and divide it by the corresponding number of pounds:

1. For 7 pounds:
   \[
   \text{Cost per pound} = \frac{\$10.43}{7} = 1.49 \, \text{(approximately)}
   \]
   
2. For 16 pounds:
   \[
   \text{Cost per pound} = \frac{\$23.84}{16} = 1.49 \, \text{(approximately)}
   \]

Thus, the cost per pound of tomatoes is approximately **$1.49**.
