ANSWER ASAP PLEASE
Carbon-14 has a half-life of 5730 years and the radiocarbon activity of wood recently cut down is 15.0 disintegrations per minute per gram of carbon. A sample of a wooden artifact is found to undergo 7.7 disintegrations per minute per gram of carbon. What is the approximate age (in years) of the artifact?
Round off the final answer to a whole number (no decimal places); no units necessary.
