how much 72% percent chocolate powder and how much 100% cocoa powder, do I have to mix to get 60 kilograms of 79% cocoa powder?

Question

Is there a formula I can use for this?

Answer 1

You want to set up a system of linear equations.

 

Let a = kg of cocoa

let e = kg of chocolate

 

We need a mixture of 60 kg, so

 

     a + e = 60

.72a + e = .79(60)

 

Combining these two equations either through substitution or elimination we have

 

.28a = (.21)(60) = 12.6

 

and a = 45

 

So we need 45 kg of cocoa and 15 kg of chocolate

Answer 2

so you need a mixture which has 79% of cocoa and 21% of chocolate? is this what you are trying to achieve?
