Question 884503
First we need to find the discount amount.  To do that take 15% of 84.  Remember 15% is the same as .15 and of means multiply.  <br>

84*.15 = 12.60<br>

So she saves 12.60 off the original price so the new sales price would be:<br>

84-12.60 = 71.40<br>

Now she pays 7% sales tax on the dress so take 7% of 71.40 and add it to 71.40.  That will get us:<br>


(0.07 * 71.40) + 71.40 
=4.998 + 71.40
=76.398 <br>

Or rounded to the nearest hundredth we get $76.40
