Astereo is marked down $75. if this is a 15% decrease find the sale price. how do you work this problem out?

The selling price is $425.

Step-by-step explanation:

Given information:

Marked down price = $75

15% decrease = $75

Let x be the market price.

Divide both sides by 0.15.

The market price is $500.

Selling price = Market price - Marked down

Selling price = $500 - $75

Selling price = $425

Therefore, the selling price is $425.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

answer: h
