16. Carbon–14 is used to estimate the age of carbon-bearing materials up to about 60,000 years old. The exponential model is given by A = Age-0.00012, The Spirit Cave Mummy which was found in Fallon, Nevada was determined to be 9,400 years old. The amount of Carbon 14 found (A) was determined to be approximately 32% of the amount present (A,) at the time of death. From this information find the half-life of Carbon–14. Show how you would set-up this problem. Then use your calculator to find the solution. Set-up: Solution:
