Question

the original price of a Bluetooth speaker was $125,but after a discount it now costs 81.25 what was the percent of change of the discount

Answer 1

Explanation:

The percent change formula is:

$\frac{\text{ end value - start value}}{\text{ start value}}\times100$

The start value is 125 and the end value is 81.25:

$\frac{125-81.25}{125}\times100=-35$

It's negative because the end value is less, since it's a discount.

Answer:

The discount was 35%
