Answer :
To determine the total amount of new flour needed, follow these steps:
1. Since each loaf requires [tex]$355$[/tex] grams of flour, if you need to make [tex]$p$[/tex] loaves, the total amount of flour required is
[tex]$$355 \cdot p.$$[/tex]
2. You already have [tex]$220$[/tex] grams of flour.
3. Therefore, the additional (new) flour you must buy is the total flour required minus the flour you already have. This can be written as
[tex]$$355p - 220.$$[/tex]
Thus, the correct expression is
[tex]$$\boxed{355p - 220}.$$[/tex]
