Kevin went to walmart and saw they where having a sale. socks 1 pack for 5 dollars, 2 tshirts for 10 dollars and tennis shoes for 10 dollars. the deal stated that if you spend 40 dollars or more you get 10 dollars back on each 10 dollars over 40 dollars you spend. what did kevin buy in order to get 60 dollars back. (he had to buy 1 at least one of each item in order to get the deal).
