Sergei runs a bakery. He needs at least 175 kilograms of flour in total to complete the holiday orders he’s received. He only has 34 kilograms of flour, so he needs to buy more.

The flour he likes comes in bags that each contain 23 kilograms of flour. He wants to buy the smallest number of bags as possible and get the amount of flour he needs.

Let represent the number of bags of flour that Sergei buys.

Which inequality describes this scenario?

34 + 23F ≤ 175
34 + 23F ≥ 175
23 + 34F ≤ 175
23 + 34F ≥ 175
