Answer:
10 cents
Step-by-step explanation:
In order to answer this question we have to find how much each chicken strip costs individually.
Let's start with the 4 piece.
To find how much each piece costs we have to divide $2.40 by 4. Like this:

In the 4 piece, every chicken strip costs .60 cents.
Now, let's do the 6 piece.
Like before we are going to divide $3.00 by 6.

In the 6 piece, every chicken strip costs .50 cents.
Therefore, customers save 10 cents when they buy the larger quantity.
