An appliance store is having a liquidation where everything in the store is 70% off the regular price. what is the price of a dishwasher that is regularly $519.89?

Here is the solution of the given problem above:
Given: 70% = percentage off the regular price
           $519.89 = regular price of a dishwasher
So to get the discounted price, we need to get first the 70% of 519.89 and it is $363.923. And then for the final price, deduct 363.923 from 519.89 and it is $155.967. Therefore, the price of the dishwasher is $155.97. Hope this answer helps.

It says in the questions that it is 6.5?
