#3**0 **

The amount of radioactive material remaing can be found using the formula:

A(t) = A_{0}·e^{kt}

where t represents the time,

A_{0} represents the original amount

A(t) represents the final amount

k represents the rate of decay (k is negative)

If you have a particular problem, post the problem.
