In an unweathered sample of igneous rock, the ratio of an unstable isotope to its stable daughter isotope is 1:15. If no daughters were present at the time the rock cooled below closure temperature (no more atoms enter the mineral structure), and the half-life of the isotope is 50 million years, how old is the rock?
