A department store has a discount on shoes based on a percentage of the price suppose one pair of shoes is marked down from $70 to $49 what is the price for a $100 pair of shoes after the discount is applied

We first need to find the difference between $70 and $49.

$70 - $49 = 21

Now we find out what percent $21 is of $70.

21/70 * 100 = 30%.

That means the discount is 30%!

Now we must find 30% of $100, which is $30.

Then we subtract $30 from $100.

$100 - $30 = 70$
