The sales price of a car is $12,590, which is 20% off the original price. what is the original price?

We know that the final price after a discount of 20% is $12,590. If the original price was x, the price after discount is 80% of x (100% - 20%). OP (original price) multiplied by (1-20/100) equals $15,737.5

I hope this helps.

20% means 20/100=1/5
We will write T as the original price
1/5xT =12,590
T/5= 12,590
T= 12,590x5=62,95
Original price is $62,95

Byou start by adding them all and setting them equal to 180 since that is half of the total degrees in a circle.(2x+8) + (3x-14) + (3x-14) = 1808x-20 = 1808x = 200x = 25
