Find how many half lives have passed
seems we are measuring in days
half life formula is as follows
A=final amount
P=initial amount
t=time in a certain units (this time, it's days)
h=time of half life
so
we are given that P=1, A=0.6, t=3
find h
subsitute
take ln of both sides
multiply both sides by h
divide both sides by ln(0.6)
use your calculator
h≈4.07075
so about 4 days is the half life
