well, you have the equation. Just plug in
Ao = 1000
t = 50
The radioactive decay of a substance is expressed by A=A^0 e^ -kt, where the initial amount A^0, decays to an amount A after t years. The positive constant k differs for each substance. Strontium 90 decays such that k=.028. Find out how much of 1,000 mg of strontium 90 remains after 50 years. Round your answer to four decimal places
-The 0 is at the bottom of the A and the -kt is an exponent to e
