Let x = the original price of a car

When it says that the sales price of a car is 20% off the original price, that means the sales price of a car is 80% of the original price. So,

(1 - 0.2) * x = 12590

0.8x = 12590

x = 12590 / 0.8

x = 15737.5

Answer:

D. $15,737.50

20% off means you are paying 100 - 20 = 80% of the original price.

20% = .20

Let

x = original price

(1 - .20)x = 12,590

.8x = 12,590

x = 12,590/.8 = $15,737.50

D. $15,737.50

20% = .20 so lets start here

x will = the original price

(1 - .20)x = 12,590 which means

.8x = 12,590 so

x = 12,590/.8 = $15,737.50

D. $15,737.50

D. $15,737.50

20% off means you are paying 100 - 20 = 80% of the original price.

hope this helps! and good luck

Well I got D.

Since 12590 is 20% off original that means it is 80% of the original price.

12590 = .80x

Solve for x and you get 17737.5

With 20% off, then the price is 80% of the original price

.8 is the rate corresponding to 80%

.8p = 12590

p = 12590/.8

p = $15.737.50

12590 is 80% of the original price

let x=original price

then

12590=.8x

divide both sides by .8

and you get x=15,737.50
