Jenny loves to chew gum, but hates losing the flavor. She
normally chews Juicy Fruit, but she wants to know if there
is another type of gum that holds the flavor longer. She
buys 4 different packs of gum, one of them being her
normal Juicy Fruit. Every day after lunch she picks one
piece of gum and chews it until it loses flavor. She times
how long it takes for the gum to lose flavor, and records
the time. She chews the same type of gum every day until
she has used up the pack, and finds an average time for
how long the flavor lasted. Then she starts chewing a new
type of gum, and continues until all 4 types have been
tested.
