a movie Theater sells park corn and bags of different size the table shows the volume popcorn The price of the bag

A movie theater sells popcorn in bags of different sizes. The table shows the volume of popcorn and the price of the bag.
Complete one column of the table with prices where popcorn is priced at a constant rate. That is, the amount of popcorn is proportional to the price of the bag. Then complete the other column with realistic example prices where the amount of popcorn and price of the bag are not in proportion.
Consider the table below,
Now to fill up the price of bag, proportional first.
It is given that when the volume of popcorn is 5 ounces, the price of the bag proportional is $3.
So, when the volume is doubled to 10 ounces, the price of the bag also gets doubled to $6.
25 ounces can be written as 5 + 5+ 5+ 5+ 5, and so since volume of 5 ounces is $3, we have 3 + 3 + 3 + 3 + 3 = $15.
38 ounces can be written as 5 + 5 + 5 + 5 + 5 + 5 + 5 + 3
5 ounces is $3 , so 35 ounces is $21. Since 5 ounces is $3, so 3 ounces will be \frac{3 \times 3}{5} = $1.8
So, 38 ounces will be $22.8.
Fill these up
Now to fill up the third column, the price of bag not proportional -
When the volume is 10 ounces, the price of the bag should be doubled, but since we are thinking about a price which is not proportional I fill up $5
When the volume of popcorn is 25 ounces, which is almost triple of $10, the price should also almost triple, to $15, but since we are thinking of a price which is not proportional, the price of the bag is only $12 and not $15.
When the volume of popcorn is 38 ounces, which is almost 8 times of 5 ounces, the price should also be increased 8 fold, and should be $24, but since we are thinking of a price which is not proportional again, the price of the bag is $20.
