Radioactive decay can be described by the following equation

ln A = ln Ao - kt

where Ao is the original amount of the substance, A is the amountof the substance remaining after time t, and k is a constant thatis characteristic of the substance.

For the radioactive isotope strontium-90 , k is 2.47E-2years-1

If the original amount of strontium-90 in a sample is 32.6 mg, howmuch time is needed for the amount of strontium-90 that remains tofall to 26.0 mg?
