To find the relationship between the cost (C) in dollars and the number of sandwiches (N) purchased, we start with the information given:

The deli sells 5 turkey sandwiches for $20.00. This indicates a linear relationship where the cost increases proportionally with the number of sandwiches bought.

The cost per sandwich can be calculated as follows:

\[
\text{Cost per sandwich} = \frac{20.00}{5} = 4.00
\]

This means each sandwich costs $4.00.

The proportional equation can be expressed as:

\[
C = kN
\]

where \(k\) is the cost per sandwich. In this case, \(k\) is $4.00. Thus, the equation becomes:

\[
C = 4N
\]

So the value that completes the equation is **4**.
