Question

a stereo is marked down $75. If this is a 15% decrease find the sale price. How do you work this problem out?

Answer 1

You can do a proportion: 75/15 = x/100
you then do 100x75 and the divide by 15 and get 500. 
15% of $500 is $75 so the sale price would be $425 I believe. 

Answer 2

Answer:

The selling price is $425.

Step-by-step explanation:

Given information:

Marked down price = $75

15% decrease = $75

Let x be the market price.

$x\times \frac{15}{100}=75$

$0.15x=75$

Divide both sides by 0.15.

$x=500$

The market price is $500.

Selling price = Market price - Marked down

Selling price = $500 - $75

Selling price = $425

Therefore, the selling price is $425.
