Answer:
This means the cost of the item to you is $57.75. You will pay $57.75 for a item with original price of $82.50 when discounted 30%. In this example, if you buy an item at $82.50 with 30% discount, you will pay 82.50 - 24.75 = 57.75 dollars.
6/8 is equivalent to 3/4, and 3/4=.75, and .75/100=75 percent. So yes, it is.
