The original cost of the cereal box is $5.00 → this represents a 100% of the price

You saved $2.00 by using a coupon, to determine the % of discount this coupon represents you can use cross multiplication:

If $5 represents 100%

$2 represents x%

Where:


\begin{gathered} (100)/(5)=(x)/(2) \\ x=((100)/(5))\cdot2 \\ x=40 \end{gathered}

The coupon represented a 40% discount on the cereal box.
