A chef used c cheese slices on a sandwich. He used 5 more pickle slices than cheese slices. Choose the expression that shows the number of pickle slices on the sandwich.

If the chef used \( c \) cheese slices on a sandwich and he used 5 more pickle slices than cheese slices, the expression for the number of pickle slices would be:

\[ c + 5 \]

So the expression showing the number of pickle slices on the sandwich is \( c + 5 \).
