Question

A sofa regularly sells for $760. The sale price is $676.40. Find the percent decrease of the sale price from the regular price.

Answer 1

11% decrease

Explanation:

Concepts:

• Percent change is the change between an old value and its new value represented as a %. If a percent change is a decrease, it means that the new value is less than the old value. If a percent change is a increase, it means that the old value is less than the new value. The formula for percent change is: (NV - OV)/OV · 100 = C, where NV = New Value, OV = Old Value, and C = Percent Change.
• The sale price is the price at which something sells or sold after the price has been reduced by sales, discounts, etc.

Solving:

Let's find the percent change by using the formula.

1. Formula for Percent Change

• (NV - OV)/OV · 100 = C

2. Plug in the values of NV and OV

• (676.40 - 760)/760 · 100 = C

3. Simplify

• -83.6/760 · 100 = C
• -0.11 · 100 = C
• -11 = C

Therefore, our percent decrease is 11% decrease.

Answer 2

Answer: (760 - 676. 40) × 100 ÷ 760 = 11%
