Question

A sofa regularly sells for 600. The sale price is 480.00. Find the percent decrease of the sale price from the regular price.

Answer 1

-20%

Explanation:

Regular price = $600

Current sale price = $480

To find the percentage decrease in this case, use percentage change formula;

Percentage change =
`(Current price - Regular price)/(Regular price)`*100

Next, plug in the numbers into the formula ;

Percentage change =
`((480 -600))/(600)*100 \\ \\ =(-120)/(600) *100\\ \\ =-0.2*100\\ \\ =-20%`

Therefore, the percentage decrease is -20%
