Academics

Question- An ancient skull has a carbon-14 decay rate of 0.80 disintegrations per minute per gram of carbon (0.80dis/minxgC ).

Question- How old is the skull? (Assume that living organisms have a carbon-14 decay rate of 15.3 dis/min?gC and that carbon-14 has a half-life of 5730 yr.)

Anyone can tell me how to solve it step by step so that I will be able to understand what is going on?
