Answer:
*4
Step-by-step explanation:
In 386750.36 years the Carbon - 14 will be 20 g in the substance
Step-by-step explanation:
Here A = 20 g
The given equation is,
A= 25e - 0.000124t
We need to find the value of t
20 = 25e - 0.000124t
20 - 25e = - 0.000124t
25e - 20 = 0.000124t
(25e - 20 ) / 0.000124 = t
t = (25e - 20) / 0.000124
t = (65.957 - 20) / 0.000124
t = 45.957 / 0.000124
t = 386750.36 years
I think the answer would be -3
