The half-life of a radioactive substance is the time required for half of a sample to undergo radioactive decay, or for the quantity to fall to half its original amount. Carbon 14 has a half-life of 5730 years. Suppose two given samples of
carbon 14 weigh 58 of a pound and 78 of a pound. Write
and solve an equation to determine the total weight w of the samples 11,460 years ago?
