Respuesta :

We will determine the remaining almond flour as follows:

*First: We determine how much does 20% of it is:

[tex]x=\frac{90\cdot20}{100}\Rightarrow x=18[/tex]

So, 20% of almond flour is 18 pounds. Now, we subtract this amount from the total amount:

[tex]r=90-18\Rightarrow r=72[/tex]

So, there are 72 pounds of almond flour left.
