100% of an item means the full number or price.
Selling Price means how much the item was sold for.
Cost Price means how much the item was originally bought for.
Percentage profit means that I sold the item for more than it was originally worth. (Selling Price > Cost Price)
Percentage loss means that I sold the item for less than it is worth. (Selling Price < Cost Price)
