The cost of Candy Bar A is displayed in the table. 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.
To find the cost per bar for Candy Bar A, we divide the cost by the quantity:
Cost per bar for Candy Bar A:

2 candy bars: $2.50 / 2 = $1.25 per bar
3 candy bars: $3.75 / 3 = $1.25 per bar
4 candy bars: $5.00 / 4 = $1.25 per bar
5 candy bars: $6.25 / 5 = $1.25 per bar
The cost per bar for Candy Bar A is $1.25.
For Candy Bar B, the equation y=x means that the cost is the same as the quantity. Therefore, the cost per bar for Candy Bar B is also equal to $1 per bar.
