To determine which candy bar is the cheapest cost per bar, we need to calculate the cost per bar for both Candy Bar A and Candy Bar B.
**For Candy Bar A:**
- The costs for different quantities are:
- 1 bar: $1.25
- 2 bars: $2.50 → $2.50 / 2 = $1.25 per bar
- 3 bars: $3.75 → $3.75 / 3 = $1.25 per bar
- 4 bars: $5.00 → $5.00 / 4 = $1.25 per bar
- 5 bars: $6.25 → $6.25 / 5 = $1.25 per bar
The cost per bar for Candy Bar A is consistently $1.25.
**For Candy Bar B:**
- The equation for Candy Bar B is \( y = x \), which means the cost per bar is $1.00 for every bar purchased:
- 1 bar: $1.00
- 2 bars: $2.00 → $2.00 / 2 = $1.00 per bar
- 3 bars: $3.00 → $3.00 / 3 = $1.00 per bar
- 4 bars: $4.00 → $4.00 / 4 = $1.00 per bar
- 5 bars: $5.00 → $5.00 / 5 = $1.00 per bar
The cost per bar for Candy Bar B is consistently $1.00.
**Comparison:**
- Candy Bar A costs $1.25 per bar.
- Candy Bar B costs $1.00 per bar.
**Conclusion:**
Candy Bar B is cheaper.
