Question

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

Answer 1

Step-by-step explanation: Using proportions, it is found that Sergei needs to buy 7 bags.

-----------

This question is solved by proportions, using a rule of three.

He has 34 kilograms of flour.

He needs 175 kilograms.

Thus, he needs to buy 175 - 34 = 141 kilograms.

Each bag contains 23 kilograms. How many bags are needed for 141 kilograms?

1 bag - 23 kilograms

x bags - 141 kilograms

Applying cross multiplication:

`23x = 141`

`x = (141)/(23)`

`x = 6.1`

Rounding up, he needs to buy 7 bags
