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\%

\begin{cases}
-yx-2x=-\underline{b}x\implies y+2=\underline{b}\\
(-2)(-y)=b\implies 2y=b

\underline{b}=b\implies y+2=2y\implies 2=y

what is b?   from the first equation in the system, y + 2 = b.
