The cost of Candy Bar A is displayed in the table. The proportional relationship between the cost and quantity for Candy Bar B is represented by the equation y = x. Which candy bar is the cheapest cost per bar? Enter 1 for Candy Bar A. Enter 2 for Candy Bar B.

Answer 1

To determine which candy bar has the cheapest cost per bar, we need to find the cost per bar for both Candy Bar A and Candy Bar B.

**For Candy Bar A:**

According to the provided table:
- For 1 bar: $1.25
- For 2 bars: $2.50
- For 3 bars: $3.75
- For 4 bars: $5.00
- For 5 bars: $6.25

Now let's calculate the cost per bar for Candy Bar A for each quantity:

1. Cost per bar for 1 bar:
\[
\frac{1.25}{1} = 1.25
\]
2. Cost per bar for 2 bars:
\[
\frac{2.50}{2} = 1.25
\]
3. Cost per bar for 3 bars:
\[
\frac{3.75}{3} = 1.25
\]
4. Cost per bar for 4 bars:
\[
\frac{5.00}{4} = 1.25
\]
5. Cost per bar for 5 bars:
\[
\frac{6.25}{5} = 1.25
\]

**Conclusion for Candy Bar A:** The cost per bar is always $1.25, regardless of the quantity.

**For Candy Bar B:**

The relationship given is \( y = x \), meaning the cost per bar for Candy Bar B is $1.00 regardless of the quantity purchased.

**Final Comparison:**
- Cost per bar for Candy Bar A: $1.25
- Cost per bar for Candy Bar B: $1.00

Since $1.00 (Candy Bar B) is less than $1.25 (Candy Bar A), **Candy Bar B is the cheaper option.**

Therefore, the answer is **2** for Candy Bar B.

Answer 3

Let's re-evaluate the calculation step by step to ensure everything is accurate.

### Candy Bar A:
From the table you provided, the costs for different quantities of Candy Bar A are:
- 1 bar: $1.25
- 2 bars: $2.50
- 3 bars: $3.75
- 4 bars: $5.00
- 5 bars: $6.25

We can calculate the cost per bar for each quantity:

- **For 1 bar**:
\[
\frac{1.25}{1} = 1.25 \text{ per bar}
\]

- **For 2 bars**:
\[
\frac{2.50}{2} = 1.25 \text{ per bar}
\]

- **For 3 bars**:
\[
\frac{3.75}{3} = 1.25 \text{ per bar}
\]

- **For 4 bars**:
\[
\frac{5.00}{4} = 1.25 \text{ per bar}
\]

- **For 5 bars**:
\[
\frac{6.25}{5} = 1.25 \text{ per bar}
\]

So, the cost per bar for Candy Bar A consistently is **$1.25**.

### Candy Bar B:
The cost for Candy Bar B is given by the equation \( y = x \). Assuming \( y \) is the total cost and \( x \) is the quantity, the cost per bar for Candy Bar B is:

- For any quantity \( x \), the total cost is \( x \) dollars, so the cost per bar is:
\[
\frac{x}{x} = 1 \text{ per bar}
\]

### Final Comparison:
- Cost per bar for Candy Bar A: **$1.25**
- Cost per bar for Candy Bar B: **$1.00**

### Conclusion:
Candy Bar B, at $1.00 per bar, is indeed cheaper than Candy Bar A at $1.25 per bar.

Thus, the correct answer is **2** for Candy Bar B being the cheaper option. Thank you for your follow-up; everything checks out correctly!
