Question

quantity ($) Cost

1 1.25
2 2.50
3 3.75
4 5.00
5 6.25

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!
