is planning a cookout. His wife has asked him to buy some hot dogs and hot dog buns. While doing this, finds out one of the mysteries of life. There are 10 hot dogs in each package, but only 8 buns in a package of buns. So he is stuck with two extra, unclothed dogs. If wants an equal number of hot dogs and buns, what is the smallest number of packages of each that he must buy?
