Paul went to the sporting goods store to buy a tennis racket. His favorite brand was having a sale that offered customers a deal to buy one racket at full price and get the second racket for half off the full price.  If he purchased two rackets that were each originally marked at a full price of $60, how much did he spend on the two rackets, in dollars? Let's think first. Chain of thought:
Half off the full price of $60 is $60 / 2 = $30 off. Thus, for the two rackets, Paul spends $60 + $60 - $30 = $90.
Therefore, the answer is 90.
