Question

If you receive a 20% DISCOUNT off an item costing $20.00, how much money do you save?

Answer 1

20% off of $20 would be $4.
I know this because all you have to do while finding percentages is to take the first number of the % and the first number of the cost which will be 2x2= $4 saved

Answer 2

It’s easy just convert the percentage to decimal by dividing by 100 and you get 0.2

Now you multiply 20x0.2= 4

You save $4
