Step-by-step explanation:

Answer 2

Yes. Total cost of the apples proportional to the total mass

Solution:

Given that,

Apples are on sale for $3.12 per kilogram

To find: Is the total cost of the apples proportional to the total mass

From given,

1 kg apple = $ 3.12

When the kilograms of apple increases, then cost also increases

For example:

consider 2 kg apple,

cost of 2 kg apple = 2 x 3.12 =  $ 6.24

cost of 3 kg apple = 3 x 3.12 = $ 9.36

From this we can say,

Cost of "n" kg apple = n x 3.12

Thus total cost of the apples proportional to the total mass
