You can put this solution on YOUR website! Let's say the original price of the car is X
and we know that if we take 20% off the original price, we are only paying 80% of the original price. Our original price was 100% and (20% + 80% = 100%)
Percentages are expressed in decimals, so 80%=.8
and .8x means 80% of original price
.8x=12590 (80% of the original cost is $12,590)
Divide both sides by .8
x=15737.50
So the originial price of the car was $15,737.50
