Answer:
The percent of change is 25%.
Step-by-step explanation:
Given:
A $525 speaker now sells for $393.75.
Now, to find the percent of change.
So, we get the difference in the amount first:
[tex]\$525-\$393.75[/tex]
[tex]=\$131.25.[/tex]
Now, to get the percent of change:
[tex]\frac{131.25}{525}\times 100[/tex]
[tex]=\frac{13125}{525}[/tex]
[tex]=25\%.[/tex]
Therefore, the percent of change is 25%.
