To determine which candy bar is cheaper per bar, we first need to calculate the cost per bar for Candy Bar A based on the given table and then for Candy Bar B based on the equation provided.
Candy Bar A:
From the table:
- Cost for 1 bar: $1.25 → Cost per bar = $1.25
- Cost for 2 bars: $2.50 → Cost per bar = $2.50 / 2 = $1.25
- Cost for 3 bars: $3.75 → Cost per bar = $3.75 / 3 = $1.25
- Cost for 4 bars: $5.00 → Cost per bar = $5.00 / 4 = $1.25
- Cost for 5 bars: $6.25 → Cost per bar = $6.25 / 5 = $1.25
Cost per bar for Candy Bar A is consistently $1.25.
Candy Bar B:
The equation given is \(y = x\) where \(y\) represents the cost and \(x\) represents the quantity. This means:
- Cost for 1 bar: $1 → Cost per bar = $1 / 1 = $1.00
- Cost for 2 bars: $2 → Cost per bar = $2 / 2 = $1.00
- Cost for 3 bars: $3 → Cost per bar = $3 / 3 = $1.00
- Cost for 4 bars: $4 → Cost per bar = $4 / 4 = $1.00
- Cost for 5 bars: $5 → Cost per bar = $5 / 5 = $1.00
Cost per bar for Candy Bar B is consistently $1.00.
Conclusion:
- Candy Bar A costs $1.25 per bar.
- Candy Bar B costs $1.00 per bar.
Candy Bar B is cheaper.
Therefore, the answer is 2.
