Answer:
Well for example most video games cost $60, so if you divide the original price by 100 and multiply it by 30, you'll get 18, so you take away that from 60, then you'll get 42.
Step-by-step explanation:
60 divided by 100 = 0.6, times that by 30 = 18, take away that from the original price which was 60, you'll get 42.
