Let x = original price
(20%)x = 0.2 x = 20% of the original price

The sales price of a car is $12,590, which is 20% off the original price, so
$ 12,590 = x – 0.2x

Multiply 10 to both sides (to simplify)
$ 125,900 = 10x – 2x

Simplify and exchange places
8x = $ 125,900

Divide
x = $ 15,737.50

Therefore, the original price is
$ 15,737.50

Look at the problem and convert key words mathematic symbols. The sale price of a car is $12,590. $12,590 is 20% off of the original price. Therefore, $12,590 is 80% of the orginal price. Look at my first equation. The .8 represents 80%, and “n” is the original price. Divide 12,590 by .8 and that gives you “n,” which is the original price.
12,590=.8n
15,737.50=n
The original price was $15,737.50, or round up to $15,738.

15,108.00 You take the 12,590 and x it by the 20% which gives you 2,518 then add it to the 12,590 and you have your answer of 15,108.

The original price is $15,100.00 . You take the sale price 12,590.00 and multiply it by 20% gives you 2518.00 Then you add that to the sale price you come to the total

Original price is: $15,737.50.
If 12,590 is the result of 20% off, then $12,590 represents the other 80% of the full price. So if you divide $12,590 by 8 you’ll get ($1573.75) which is 10% of the total price. Multiply $1573.75 by 2 and that gives you 20% of the total price ($3147.50). $12,590 + $3147.50 = $15,737.50.
To check the answer: divide $15,737.50 by 10 and you will get what 10% of $15,737.50 is ($1,573.75). Multiply that by 2 and you get ($3,147.50) which represents 20%. Does $15,737.50 minus $3,147.50 equal $12,590???

The sale price is 20% off so it is 80% of the original price. X is the original price. 80% of X is the sale price, so to solve for X, you divide the sale price by 80% (0.80).

(1-0.20)X = $12,590
X=$12,590/0.80
X=$15,737.50

15737.5

Original Price * 80% = 12590
OP * .8 = 12590
OP = 12590 / .8
OP = 15737.5

That means $12590 is 80% of the cost price.
So the required cost price is [12590*100/80]=$15737.50

x is the original price

12590 = x – .2 * x
12590 = .8x
12590 / .8 = x
15737.5 = x

$ 15,737.50

$ 12,590.00 divided by .80 = $ 15,737.50 x 20% = 3,147.50

(3,147.50)

= $ 12,590.00
