please explain why you got the answer / show your work. ty <3

non-proportional

Step-by-step explanation:

A proportional pricing method would ensure that the various quantities of milk have the same relative price relating to their quantity. For instance, a half gallon of milk should be half the price of a full gallon of milk for it to be Proportional.

In this example, a gallon costs $3.89. If it were proportional then a half gallon would cost;

= 3.89/2

= $1.95

It instead costs $1.99 which means that it is Non-Proportional.
