The proportional relationship between the cost and quantity for Candy Bar B is represented by the equation y=x . Which candy bar is the cheapest cost per bar? Enter 1 for Candy Bar A. Enter 2 for Candy Bar B. (1 point)

Answer 1

To determine which candy bar is the cheapest cost per bar, we need to find the cost per bar for both Candy Bar A and Candy Bar B.

For Candy Bar A, we can observe the cost at different quantities:

- For 1 bar: $1.25
- For 2 bars: $2.50
- For 3 bars: $3.75
- For 4 bars: $5.00
- For 5 bars: $6.25

Now we calculate the cost per bar for Candy Bar A:

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

The cost per bar for Candy Bar A is constant at $1.25.

For Candy Bar B, the relationship is given by the equation \(y = x\), where \(y\) is the cost and \(x\) is the quantity. This means:

- For 1 bar: Cost = $1 (1 x $1)
- For 2 bars: Cost = $2 (2 x $1)
- For 3 bars: Cost = $3 (3 x $1)
- For 4 bars: Cost = $4 (4 x $1)
- For 5 bars: Cost = $5 (5 x $1)

Now we calculate the cost per bar for Candy Bar B:

- Cost per bar for 1 bar: $1.00 / 1 = $1.00
- Cost per bar for 2 bars: $2.00 / 2 = $1.00
- Cost per bar for 3 bars: $3.00 / 3 = $1.00
- Cost per bar for 4 bars: $4.00 / 4 = $1.00
- Cost per bar for 5 bars: $5.00 / 5 = $1.00

The cost per bar for Candy Bar B is constant at $1.00.

Now we compare the two:

- Cost per bar for Candy Bar A: $1.25
- Cost per bar for Candy Bar B: $1.00

Since $1.00 (Candy Bar B) is less than $1.25 (Candy Bar A), Candy Bar B is the cheapest.

So the answer is **2** for Candy Bar B.
