GamesOnly is having a “30% Off Everything!” sale. They have a PS4 on sale for $182. What was the original price?
Setler79 [48]

Answer:

original price = 260

Step-by-step explanation:

original price * percent off = discount

then subtract the discount

original price - discount = new price

so

original price - original price * percent off = new price

factor out the original price

original price( 1- percent off) = new price

original price = new price/ ( 1- percent off)


lets put in what we know

original price = 182/(1-.30)

original price = 182/(.7)

original price = 260

On a floor plan drawn at a scale of 1:100, the area of a rectangular room is 30
Troyanec [42]
Assume that the dimensions of the room in the plan are a (width ) by b (length),

such that a*b=30.

Since the scale is 1:100, a represents 100a, and b represents 100b.

So the actual dimensions are 100a by 100b.

The area is 100a*100b=a*b*10,000=30*10,000=300,000 (square units)



Answer:  300,000 (square units)

Divide both sides by -2 to isolate x:

x = -1
