Apples are on sale for $3.12 per kilogram. Is the total cost of the apples proportional to the total mass?
2 answers:
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.
Answer:
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.
