After applying the coupon, the large pizza price came down to $13.00 from $16.25
We need to figure out the percentage change of this.
The formula for percent change is:
The amount of change (decrease) is:
16.25 - 13.00 = 3.25
The original amount is:
16.25
We substitute these information into the formula and figure out our answer:
[tex]\begin{gathered} \frac{3.25}{16.25}\times100 \\ =0.2\times100 \\ =20\% \end{gathered}[/tex]Thus, the decrease is 20%.
We can say that the coupon was 20% off coupon.
