Question

You go shopping and buy a gift for a friend, but on the day
before you're going to give it to him, you notice that he
already has exactly what you bought him! You take the gift
back to the mall, but you lost your receipt. The cashier
says that you can only get back cash for the lowest
amount that the item sold for. The item was originally $50
and sales tax in your area is 9.5%. It went on sale on four
different occasions. Keep in mind that when an item goes
on sale, it is taxed first and then the discount is taken. The
first sale was 10% off. The second sale was no tax. The
third sale was buy 3, get 1 half off. The last one was buy
anything over $40 and get a $5 gift card. How much cash
will you get back?​
