i think that you should ask google for the answer to that problem because if we don't know it google does

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

if you was gonna solve for a, a is a   < -12

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
