Question

A dress cost $63. If the store is having a 20% off sale, how much does the dress cost now? ( the answer is $50.40 but I need to know HOW to do it.)

Answer 1

Answer:

$50.40

Step-by-step explanation:

Make an equation:

                 20%  

------    =    -------        

63              100%      

1.  63 x 20= 1,260
2. 1,260/100=12.6        
3. 63 - 12.6 = 50.40
