Lets try to create a simple ratio based from the information that we have. Lets call the amount for 2 packs X since is unknown.

So if 3 packs of paper is worth 4.98.

That means that 2 packs of paper is worth X.

Lets cross multiply, 3 times x equal to 2 times 4.98.

3x=2*4.98

3x=9.96

Divide both sides with 3.

3x/3 = 9.96/3

x=3.32
