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?

How much is the second racket discounted? ** Half off the full price of $60 is $60/2=$<<60/2=30>>30 off.
How much did Paul spend on the two rackets? ** Thus, for the two rackets, Paul spends $60+$60-$30=$<<60+60-30=90>>90.
