Formula: Radioactive Decay Formula
  
Given: There are 12 grams of Americium-241.
Americium-241 has a half-life of 432.2 years.
  
Find:  Use the formula above to calculate the time it would take for the given mass to degrade down to 0.11 grams. Calculate the solution for 't' to the nearest tenth using logarithms.
  
Solution:   t = years
