Answer :
Sure, let's go through the problem step by step to find the correct inequality.
1. Understanding the problem:
- Sergei needs at least 175 kilograms of flour in total.
- Currently, he has 34 kilograms.
- He can buy more flour in bags, each containing 23 kilograms.
2. Defining the variable:
- Let [tex]\( F \)[/tex] represent the number of bags of flour Sergei buys.
3. Setting up the inequality:
- The total amount of flour Sergei will have after buying [tex]\( F \)[/tex] bags is:
[tex]\[
\text{Total flour} = \text{Current flour} + \text{Flour per bag} \times F
\][/tex]
- Substituting the given values:
[tex]\[
\text{Total flour} = 34 + 23F
\][/tex]
4. Formulating the condition:
- Sergei needs the total amount of flour to be at least 175 kilograms. Thus, we set up the inequality:
[tex]\[
34 + 23F \geq 175
\][/tex]
5. Choosing the correct inequality from the given options:
- The inequality that fits this scenario is:
[tex]\[
34 + 23F \geq 175
\][/tex]
Thus, the correct answer is:
[tex]\[
\boxed{B}
\][/tex]
