- 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:
[tex]23x = 141[/tex]
[tex]x = \frac{141}{23}[/tex]
[tex]x = 6.1[/tex]
Rounding up, he needs to buy 7 bags.
