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.
