how would we know that is correct if we wouldn't first prove it?

okay, so we have got 76 lbs of cocoa powder in total. We also know that every day she uses THE SAME amount of it.

now, in 10 days she used   $ (76-20.2) \ \text{lbs}$  which is equal to $ 55.8 \ \ \text{lbs} $

since she used that much for 10 days where everyday she used the same ammount, we can set up this equation:
 
$ 55.8 \ \ \text{lbs} =  10 \times n  $ where $n$ is the ammount se used everyday

therefore  $ \dfrac{55.8 \ \ \text{lbs}}{10} =   n  $   so    $\boxed{5.58 =n}$
