The half life formula is :

where N(t) = remaining quantity after t years
No = Original Quantity
t = time in years
T = half life in years
From the problem, we have :
N(t) = 30 grams
No = 100 grams
T = 674
Solve for t :

Take ln of both sides :

The answer is t = 1170.71 years
When looking at a # line it goes up or down so ex of a # line -3, -2, -1, 0, 1, 2, 3 so on a # line 11.1, 11.2, 11.3, 11.4, 11.5, 11.6 ,11.7 so going from zero 11.6 is larger than 11.3 so 11.6 is greater than 11.3
