Exponential decay is a very common process especially when we are talking about radioactive materials. So, there is already a common formula for this type of behavior which is written below:A = Pe^-rtwhereA is the amount left after time tP is the initial amount at t=0r is the rateSubstituting the values,A = (9575 kg)(e^-0.12*5)A = 5,254.87 kg...
