    Yes.

    Step-by-step explanation:

    We have given the price of apple per kilogram.

    Hence, price of total apples is equal to the product of number of apples and price per kilogram of apple.

    Answer: Yes

    Tc = 3.12m

    Therefore, total cost of apple is directly proportional to the total mass with a proportionality constant of 3.12.

    Step-by-step explanation:

    The total cost of the apples is proportional to the total mass. The product of the mass and the cost per mass ($3.12) gives the total cost.

    It can be shown using the equation below

    Tc = c*m

    Where Tc = total cost

    c = cost per unit mass

    m = total mass in kilogram

    Tc = 3.12m

    Therefore, total cost of apple is directly proportional to the total mass with a proportionality constant of 3.12.
