Frequently Asked Questions (FAQ)

What does “percent” actually mean? The word “percent” comes from the Latin per centum, which literally translates to “by a hundred.” It is a way of expressing a number as a fraction of 100. For example, 20% means 20 out of 100.

How do I calculate a percentage discount? To find a discount, you can use the “What is X% of Y?” feature. Enter the discount percentage as X and the original price as Y. The result is how much money you save. Subtract that from the original price to get your final cost.
