Final answer:
The total cost of the apples is directly proportional to the amount bought.
Step-by-step explanation:
The relationship between the total cost of the apples and the amount of apples bought can be described as a direct proportion. This means that as the amount of apples bought increases, the total cost of the apples also increases at the same rate.
For example, if you buy 2 pounds of apples, the total cost would be $0.68 x 2 = $1.36. If you buy 3 pounds of apples, the total cost would be $0.68 x 3 = $2.04.
Therefore, option A is the correct answer: The total cost of the apples is directly proportional to the amount bought.
