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 cheapesst cost per bar?
Candy bar A is cheaper than candy bar B per bar.
Assuming the cost of candy bar A is $1.20 per bar, and the cost of candy bar B is represented by the equation y = x, where x is the quantity of candy bar B and y is the cost of candy bar B. Since the cost of candy bar B is directly proportional to the quantity, the cost per bar of candy bar B will be the same as the quantity. For example, if the quantity of candy bar B is 5, then the cost per bar of candy bar B will be $5.
Therefore, since the cost per bar of candy bar A is $1.20 and the cost per bar of candy bar B is equal to the quantity of candy bars, candy bar A is cheaper per bar.
