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.
