Answer:
$350
Step-by-step explanation:
If $280 is the 20% savings from the original price, it is 80% of original price.
280 / 0.8 = 350
From this equation, we can know that 350 is 100% of original price, which makes it the original price.

Answer:
Step-by-step explanation:
The given expression is x- 
= 2
and we have to solve this for the value of x,
( x- ) = (2)
x² - 15 = 2x
x² - 2x - 15 = 0
x² - 5x + 3x - 15 = 0
x ( x-5 ) + 3(x - 5) = 0
( x+3 )( x-5 ) = 0
( x+3) = 0
x = -3
or ( x- 5 ) = 0
x = 5
Therefore, x = -3 and 5 will be the solution.
Option E is the answer.
Answer:
460 ft^2 of carpet will be replaced
Step-by-step explanation:
You need to find the area of the room and then take away the area of the six bookcases
<u>Area of the room</u>
20*20=400ft^2
35-20=15ft
(15*20)/2=150ft^2
400+150=550ft^2 total room area
<u>Area of bookcases</u>
2.5*6*6=90ft^2 total bookcase area
<u>room area - bookcase area = carpet area</u>
550-90=460ft^2
