There needs to be a math/homework help sticky/'Official' thread that gets buried once no one needs it anymore.
Anyway I'm having a total brain fart right now and need someone to point out how to do this again
The table below gives information about the radioactive decay of carbon-14. Part of the table has been deliberately left blank.
After how many years will 1/128 gram of the original carbon-14 remain?
1. 22,800 yr
2. 28,500 yr
3. 34,200 yr
4. 39,900 yr
