Ajacket is on sale for 20% off the regular price. the sale price is $50.00. what is the regular price of the jacket?

So it is essentially 80% of the original price , so what i would do is divide it by 8 and then times it by 10 to get the original price , in this case it will be 50/8 (6.25) and then times 6.25 by 10 which will give you the original price of $62.50
