Jeans are reduced from 28.00 to 18.20 during a sale at a department store. What percentage was the original price reduced?

Natali [406]

Answer:

The original price was reduced 35%

Step-by-step explanation:

we know that

Jeans are reduced from $28.00 to $18.20

In this problem

The original price of 28.00 represent 100%

using proportion

Find out what percentage represent the difference between the original price and the new price

$\frac{28}{100}=\frac{28-18.20}{x}\\\\x=100(9.8)/28\\\\x=35\%$

therefore

The original price was reduced 35%
