High School

Sergei runs a bakery and needs at least 175 kilograms of flour to complete the holiday orders he's received. He currently has 34 kilograms of flour, so he needs to buy more.

The flour he prefers comes in bags that each contain 23 kilograms. He wants to buy the smallest number of bags possible to get the required amount of flour.

Let [tex]F[/tex] represent the number of bags of flour that Sergei buys.

Which inequality describes this scenario?

Choose one answer:

A. [tex]34 + 23F \leq 175[/tex]

B. [tex]34 + 23F \geq 175[/tex]

C. [tex]23 + 34F \leq 175[/tex]

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]
