To find the cost per bar for each candy bar, we need to divide the cost by the quantity for each candy bar.
For Candy Bar 1:
Cost per bar = Cost / Quantity
For 1 candy bar, cost per bar = 1.25 / 1 = 1.25
For 2 candy bars, cost per bar = 2.50 / 2 = 1.25
For 3 candy bars, cost per bar = 3.75 / 3 = 1.25
For 4 candy bars, cost per bar = 5.00 / 4 = 1.25
For 5 candy bars, cost per bar = 6.25 / 5 = 1.25
For Candy Bar 2:
Cost per bar = Cost / Quantity
For any number of candy bars, the cost per bar will always be the same as the quantity, according to the equation y = x.
Therefore, both Candy Bar 1 and Candy Bar 2 have the same cost per bar, which is 1.25.
