A pair of Levi 501 Jeans go on sale from $50 to $45. What is the percent decrease?

Answer 1

Savannah Anderson

The jeans are discounted at #10%# off.

$45 is what percent of$ 50

#$45 = n%($50)#

#($45)/($50) = (n%cancel($50))/(cancel($50))#

#.90 = n%#

#90% = n#

Since the original price of $50 represents the 100% price and$ 45 represents 90% of that price the discount is

#100% - 90% = 10%#

There is a 10% discount on the jeans.

To calculate the percent decrease:

Find the decrease in price: $50 -$ 45 = $5
Calculate the percent decrease: (Decrease ÷ Original Price) × 100%
Substitute the values: ( $5 ÷$ 50) × 100% = 10%

The percent decrease is 10%.
