7. Your favorite store is having a 10%-off sale, meaning that the store will take 10% off the price of each item you buy. When the clerk rings up your purchases, she takes 10% off the total (before tax), rather than 10% off each item. Will you get the same discount either way? Is there a property of arithmetic related to this? Explain!
