Question

A new television is on sale for $680.00, which is 20% off of its original price. What was the original price of the television?

Answer 1

x= original price
% off= 20%
Sale $= $680

STEP 1:
Find discount amount

Discount Amount= % off * Original $
= 20% * x
change % to decimal (% ÷ 100)
= 0.20 * x
= 0.20x

STEP 2:
Find sale price

Sale Price= Original $ - Discount
= x - 0.20x
= 0.80x

STEP 3:
Sale= $680= 0.80x
Solve for x

$680= 0.80x
divide both sides by 0.80
$680/0.80= x
$850= x

ANSWER: The original price is $850

Hope this helps! :)
