To determine which candy bar is cheaper per bar, we need to calculate the cost per bar for each candy bar.
For Candy Bar A:
- The table shows that the cost for different quantities is:
- 1 bar = $1.25
- 2 bars = $2.50
- 3 bars = $3.75
- 4 bars = $5.00
- 5 bars = $6.25
To find the cost per bar for Candy Bar A:
- For 1 bar: $1.25 / 1 = $1.25
- For 2 bars: $2.50 / 2 = $1.25
- For 3 bars: $3.75 / 3 = $1.25
- For 4 bars: $5.00 / 4 = $1.25
- For 5 bars: $6.25 / 5 = $1.25
So, the cost per bar for Candy Bar A is consistently $1.25.
For Candy Bar B:
- The equation y = x implies that the cost per bar is $1 for any quantity (since every quantity x has a corresponding cost y equal to x).
To summarize:
- Cost per bar for Candy Bar A = $1.25
- Cost per bar for Candy Bar B = $1
Since $1 (Candy Bar B) is cheaper than $1.25 (Candy Bar A), the cheapest cost per bar is for Candy Bar B.
So, the answer is 2 for Candy Bar B.
