How many kg of bleached flour which costs $8/kg must be added to 14 kg of unbleached flour which costs $5/kg to make baking flour which costs $6/kg?

Respuesta :

  • Cost of unbleached flour=14(5)=70

Now

Let required bleached flour be x kg

Then

[tex]\sf\longmapsto 8x+70=6x[/tex]

[tex]\sf\longmapsto 8x-6x=70[/tex]

[tex]\sf\longmapsto 2x=70[/tex]

[tex]\sf\longmapsto x=35kg[/tex]

Answer:

  • 7 kg

Step-by-step explanation:

Let the added flour is x kg.

We have following equation showing the total amount:

  • 8x + 14*5 = (14 + x)*6
  • 8x + 70 = 6x + 84
  • 8x - 6x = 84 - 70
  • 2x = 14
  • x = 7
