Answer 1

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

For Candy Bar A:

• The cost per bar is calculated by taking the total cost divided by the quantity.

From the table:

1. For 1 Candy Bar A: Cost = $1.25 → Cost per bar = $1.25 / 1 = $1.25
2. For 2 Candy Bar A: Cost = $2.50 → Cost per bar = $2.50 / 2 = $1.25
3. For 3 Candy Bar A: Cost = $3.75 → Cost per bar = $3.75 / 3 = $1.25
4. For 4 Candy Bar A: Cost = $5.00 → Cost per bar = $5.00 / 4 = $1.25
5. For 5 Candy Bar A: Cost = $6.25 → Cost per bar = $6.25 / 5 = $1.25

The cost per bar for Candy Bar A is consistently $1.25.

For Candy Bar B:

• The equation representing the cost is \( y = x \), which means the cost per bar is $1.00 (since for each quantity of 1, the cost is $1.00).

Now, comparing the two:

• Candy Bar A: $1.25 per bar
• Candy Bar B: $1.00 per bar

Candy Bar B is cheaper (costing $1.00 per bar) compared to Candy Bar A (costing $1.25 per bar).

Thus, the answer is 2 for Candy Bar B.
