**Answer:**

**Angelina should buy 9 packs of pens and 8 packs of pencils.**

**Step-by-step explanation:**

Each pack of pens = 8 pens

Each pack of pencils = 9 pencils.

Also we know that, **Commutative Property of Multiplication** states that

** a x b = b x a** for any two numbers a and b.

So, **8 x 9 = 72 = 9 x 8 **

Hence, she should buy **9 packs of pens**, so she will have 9 x 8 = **72 pens.**

And she should buy **8 packs of pencils**, she will have 8 x 9 = **72 pencils.**
