Suppose the flavor of gum you are chewing can have a rating from 0 to 1, where 0 = no flavor at all and 1 = the best possible flavor (that is, when you first start to chew it).
Now assume that the gum company announces in the advertising that the flavor has a half-life of 35 minutes.
If you have been chewing on this particular flavor of gum for a total of 90 minutes, what would be the fraction of the original flavor rating?
(Round to the nearest hundredth.)
