Step-by-step explanation:

We calculate the cost of a gram of cat food for each package.

Pack 1: Cost of 1 gram = total cost / number of grams

= 39.99 / (24 * 250)

= $0.00665 '

Pack 2: The cost is  24.99 / (12 * 300)

= $0.00694.

In a similar way

Pack 3:  The cost is $ 0.0722

Pack 4: The cost is $0.00642 .

So the answer is

4123

all it means is function 3
