A piece of furniture has a retail price of $3,200 and is on sale at a 30% discount. How much money will be saved if the piece of furniture is purchased at the sale price?

$960 will be saved

Step-by-step explanation:

Retail Price = $3,200

Sale at 30% discount = ?

First find the 30% of $3,200

= 0.30 x 3,200

= $960

The sale price $3,200 - $960 = $2,240

The retail price is $3,200 and the furniture was on sale for $2,240

∴ $960 will be saved (difference between the retail price and sale)

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:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
