For times that you can divide wholely into...for example Halflife of 60 seconds, find blah blah amount in 3 minutes Just make a table Time Amount Remaining 0 100% 60 sec 50% etc etc For more complicated problems, resort to the exponential decay formula: The halflife formula is Nt = No(1/2)^(T/Tt), where Nt is the quantity that still remains and has not yet decayed No is the initial quantity of the thing that will decay T is the amount of time that has passed Tt is the halflife

the equations my teacher gave to me were t(1/2)=0.693/K and ln[A]=Kt+ln[Ao]. How would i use those in a story problem?

t(1/2)=0.693/K and ln[A]=Kt+ln[Ao] are equations for a first order reaction calculating the half life from this is easy, just find K notice that ln[A]=Kt+ln[Ao] looks like y = mx+b
