Question

Walmart is advertising a sale where all Lego sets are 15% off. Mrs. Snyder decides to purchase a Lego set that originally cost $39. What will Mrs. Snyder pay for the Lego set on sale?

Answer 1

So this is super easy :) Simply turn 15% into a decimal 0.15
5.85 is how much money she doesn't have to pay. 
So she has to pay 33. 15

Answer 2

Well If you start with $39 you will need to turn your 15% into a decimal which is .15 Multiply that by your 39 and you get 5.85 that is your discount price so now subtract that from 39 to get 33.15
