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
