Answer 1

To determine the cost of 12 apples given that 8 apples cost $2, we can set up a simple table and find a scale factor.

First, we can find the cost per apple:

- Cost for 8 apples = $2
- Cost per apple = $2 / 8 apples = $0.25 per apple

Now, we can set up a table:

| Number of Apples | Price |
|------------------|--------|
| 8 | $2.00 |
| 12 | $3.00 |

To find the price for 12 apples using the scale factor:

1. Calculate the scale factor: \( \frac{12}{8} = 1.5 \).
2. Now, multiply the price for 8 apples by the scale factor:
\[
2 \times 1.5 = 3
\]

So, the price for 12 apples will be $3.00.

The completed table looks like this:

| Number of Apples | Price |
|------------------|--------|
| 8 | $2.00 |
| 12 | $3.00 |
