While in the upper peninsula, you have found an unusual fossil in a rock layer that you are really interested in. You are able to use radioactive dating to date the layer that the fossil is in. Your sample originally contained 1 gram of radioactive potassium 40, and only 0.25 grams of potassium 40 are left. The half life of potassium 40 is 1.25Gyr. How old is the rock in Gyr, to within 10 percen precision?
