A department store has a discount on shoes based on a percentage of the price. Suppose one pair of shoes is marked down from 80 to 64. What is the price for a $200 pair of shoes after the same discount is applied.

Respuesta :

Answer:

Discounted price = $160

Step-by-step explanation:

Let x be the discounted price of shoes.

Given:

A department store has a discount on shoes based on a percentage of the price.

and marked down on one pair of shoes is $80 to $64.

So, the discounted rate = 80 - 64 = 16

therefore, the percent of discount is.

% value  [tex]=\frac{discounted\ rate}{original\ rate}\times 100[/tex]

% value  [tex]=\frac{16}{80}\times 100[/tex]

% value [tex]=\frac{16\times 100}{80}[/tex]

% value [tex]=\frac{16\times 10}{8}[/tex]

% value [tex]=2\times 10[/tex]

% value = 20%

Find the price for a $200 pair of shoes after the same discount is applied.

So the discount is 20% and the discounted price of the shoe is 80% of $200.

% value  [tex]=\frac{discounted\ price}{original\ price}\times 100[/tex]

80 [tex]=\frac{x}{200}\times 100[/tex]

[tex]x=\frac{80\times 200}{100}[/tex]

[tex]x=80\times 2[/tex]

x = $160

Therefore, the discounted price of the shoe is $160.
