Math Problem Statement
After some ancient bones were excavated, carbon was taken from one of the bones to find that there was 87% as much Superscript 14 Baseline Upper C as from current bones. The decay constant of Superscript 14 Baseline Upper C is k almost equals 0.0001216, for time in years. How many years old is the bone?
