Jimmy and Tonya both like collecting matchbooks and stamps. Tonya and Jimmy decide to trade some stamps and matchbooks. They have each decided that one stamp is worth 12 matches. Each matchbook contains 24 matches. If Tonya arrives with 13 stamps, Jimmy has 5 matchbooks, and Jimmy trades all his matchbooks for stamps, how many stamps does Tonya have left?
Jimmy has 120 matches because 5 times 24 equals <<5*24=120>>120.
Jimmy trades this for 10 stamps because 120 divided by 12 equals <<120/12=10>>10
Tonya has 3 stamps left because 13 minus 10 equals <<13-10=3>>3.
