Problem 403. Einsteinium-253 decay

Radioactive Einsteinium-253 has a half-life of 1,768,608 seconds. Given 1000mg of Einsteinium-253 at t=0 days, how much is left after 50 days?

EX: >> decay(50)

184

HINT: find k, then decay(50)

Use: decay(t)=10^3*e^(k*t)

NB: make sure you round your answer up to the next highest integer.
