Question

Here are the prices for cheese pizza at a certain pizzeria:Large Pizza = $16.25You had a coupon that made the price of a large pizza $13.00. For what percent off was the coupon?Do not include the percent sign (%) in your answer.

Answer 1

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:

`\begin{gathered} (3.25)/(16.25)*100 \\ =0.2*100 \\ =20\% \end{gathered}`

Thus, the decrease is 20%.

We can say that the coupon was 20% off coupon.
