Answer 1

To determine which candy bar is cheaper per bar, we need to calculate the cost per bar for Candy Bar A and compare it to Candy Bar B.

**Cost per bar for Candy Bar A:**
- For 1 bar: $1.25 / 1 = $1.25 per bar
- For 2 bars: $2.50 / 2 = $1.25 per bar
- For 3 bars: $3.75 / 3 = $1.25 per bar
- For 4 bars: $5.00 / 4 = $1.25 per bar
- For 5 bars: $6.25 / 5 = $1.25 per bar

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

**Cost per bar for Candy Bar B:**
The equation for Candy Bar B is given as y = x, which means:
- For 1 bar: $1 / 1 = $1.00 per bar
- For 2 bars: $2 / 2 = $1.00 per bar
- For 3 bars: $3 / 3 = $1.00 per bar
- Continuing this, the cost per bar remains $1.00 for any quantity.

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

Since $1.00 (Candy Bar B) is cheaper than $1.25 (Candy Bar A), the answer is:

**2 for Candy Bar B.**
