Question 1033510: During a sale at a bookstore, Joseph buys a book at full price. He is given a 50 percent discount on the second book of equal or less value. If Joseph buys two books with a full price of $15 and $10 respectively, by what percent is the total cost of the two books reduced during the sale?

In this example, the discount is only applied to the second book. So Joseph has to pay:
$15 + .5($10), or $20 total.
Since the books normally cost $25 total normally, Joseph paid $20/$25%, or 80% of both books (saving 20%)!!!!!!!!
