Question 10 of 10 • College Prep Math B - IC26

A piece of charcoal was unearthed at an archeological site and found to contain 10% of its original carbon-14. The half-life of carbon-14 is 5,730 years. This means that after 5,730 years, only half of the original amount of carbon-14 will remain. Which equation can be solved to determine the age of the charcoal?

Answer

0.10Ao = Aoe0.000121t

Ao = 0.10Aoe0.000121

0.10Ao = Aoe –0.000121t

Ao = 0.10Aoe –0.000121t
