Hillary bought an outfit for her graduation. The outfit was on sale for 30% off. She saved $36.00.

a) What was the original price of the outfit?
b) How much did she pay for the outfit, including 15% sales tax?

a)  $36  must  be  30%   of  the original  cost

 

So

 

.30C  =  36    where C is the original cost

 

C  = 36  / .30  =   $120  original cost

 

 

b)  Actual cost  to her before  taxes = 120  -30   = $90

 

90 * (1.15)  = $103.50  =   total cost to her after taxes
