Answer:
The difference in the cost of the candies, using a proportional relationship, is given by the following option:
Peanut brittle costs $0.60 more per ounce than almond bark.
What is a proportional relationship?
A direct proportional relationship is defined when the output variable y is calculated with the multiplication of the input variable x and the constant of proportionality r as follows:
y = rx.
In the context of this problem, the variables are defined as follows:
Variable y: cost of the candy.
Variable x: weight of the candies.
Constant r: cost of each ounce.
For Peanut Brittle, the cost per ounce is given as follows:
r = 10/10 = $1.
For Almond Bark, the cost per ounce is given as follows:
r = 8/5 = $1.6.
The difference of these costs is given as follows:
1.6 - 1 = $0.6.
Hence the correct option is given as follows:
Peanut brittle costs $0.60 more per ounce than almond bark.
