Exponential and Logarithmic Models · Exercise 40

Use this scenario: A tumor is injected with grams of Iodine-125, which has a decay rate of per day.

A wooden artifact from an archeological dig contains 60 percent of the carbon-14 that is present in living trees. To the nearest year, about how many years old is the artifact? (The half-life of carbon-14 is years.)

Its source prints no answer for this problem, so there's nothing to check against.
