You need to make [tex]p[/tex] loaves of bread. Each loaf requires 355 grams of flour. You already have 220 grams at home.

Choose the expression for the total amount of new flour you need to buy.

A. [tex]\frac{p}{355} + 220[/tex]

B. [tex]355p - 220[/tex]

C. [tex]\frac{p}{355} - 220[/tex]

D. [tex]355p + 220[/tex]

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]
