But they want to determine whether the fossil is authentic before they report their discovery to ABC's Nightline. Fortunately, one of the scientists is a graduate of ATU's Math 3163, so he calls upon his experience as follows: The radioactive substance (Carbon 14) has a half-life of 5730 years. By measuring the amount of Carbon present in a fossil, scientists can estimate how old the fossil is. Analysis of the Flintstone bowling ball determines that 15% of the radioactive substance has already decayed. How old is the fossil?arrow_forward
