You can put this solution on YOUR website! The decay of 422 mg of an isotope is given by , where t is time in years. Find the amount left after 17 years. Does anybody have any pointers about how to input these values on a scientific calculator?
On a TI-83 or 84, type this on the main screen:
422e^(-0.016*17)
Press ENTER
and read 321.5024982 or about 321.5 mg left
