Maria paid $28.00 for a jacket that was discounted by 30% What was the original price of the jacket

Maria's original jacket price was $40.

Step-by-step explanation:

Maria paid $ 28.00 for a jacket that was 30% off, so we know Maria paid 70% of the original jacket price. From now on, to find the original jacket price we just need to make a simple calculation, which consists of multiplying 28 by 100 and dividing the result by 70.

28$ x100 = 2800$

2800$ / 70 = 40$
