# A Car Sells For \$12,590 , Which Is A 20% Off The Original Cost. What Is The Original Cost?

(original cost) - (original cost)*20% = \$12,590    (the given information)
(original cost)(100% - 20%) = \$12,590    (factor)
(original cost)(80%) = \$12,590    (subtract the percentages)
(original cost)(80/100) = \$12,590    (convert to fraction)
(original cost)(.80) = \$12,590    (convert to decimal)
(original cost) = \$12,590/.80    (divide both sides by .80)
(original cost) = \$15,737.50

Thank you
Original price is 100% and discount price is 20% off so it is 80% which is 12590. Simply how you take out percentage you multiply the original price with 20% or what ever . In adding just do your math 100% - 20%= 80% so 12590/.80(discount price 80%)=15737.5 . Its that simple

\$ 15,737.50

( 1- p)* Or = S

p is the percentage off (20)
S is the sales price \$12,590
Or is the original price.

Solve for Or:   Or = S/(1-p)  = 12,590/(0.20) = 15,737.50

P is the percentage off, expressed as a decimal (.20)≠(20)
The formula is correct, but (1-p)≠(0.20). (1-p) = (0.80)
