Question

En una tienda de electrodomésticos, un refrigerador costaba $8,900 y rebajaron su precio a $7,120 ?Cuál fué el porcentaje que le rebajaron?

Answer 1

Answer:

$20\%$

Step-by-step explanation:

The question in English is

In one appliance store, a refrigerator cost $8,900 and they lowered it to $7,120. What percentage did they lower?

we know that

$8,900 ------> represent the 100%

so

by proportion

$\frac{100\%}{\ 8,900}=\frac{x\%}{\ 7,120}\\ \\x=7,120*(100\%)/8,900\\ \\x=80\%$

therefore

the percentage is equal to

$100\%-80\%=20\%$
