apples are on sale for $3.12 per kilogram.\nis the total cost of the apples proportional to the total mass?\nchoose 1 answer:\na yes\nb no

Answer

Explanation:

Step1: Define the relationship

Let the mass of apples be (m) (in kilograms) and the total cost be (C). The cost formula is (C = 3.12m).

Step2: Check proportionality

For two quantities (y) and (x) to be proportional, the relationship must be (y=kx) where (k) is a non - zero constant. Here, (C) (total cost) and (m) (mass) follow (C = 3.12m), with (k = 3.12) (a constant).

Answer:

A. Yes
