Answer :
Answer:
-20%
Step-by-step explanation:
Regular price = $600
Current sale price = $480
To find the percentage decrease in this case, use percentage change formula;
Percentage change = [tex]\frac{Current price - Regular price}{Regular price}[/tex]*100
Next, plug in the numbers into the formula ;
Percentage change = [tex]\frac{(480 -600)}{600}*100 \\ \\ =\frac{-120}{600} *100\\ \\ =-0.2*100\\ \\ =-20%[/tex]
Therefore, the percentage decrease is -20%
