C
115
Explanation:
I am SURE I am correct in this please inform me if I make a mistake but I only answer when I’m SURE UNLIKE SOME PEOPLE DAG.
Answer:
C, P(t)=120(1/2)^t/1620
The answer for the follow-up question is 115.
Explanation:
After 100 years, about ✔ 115 grams of the sample will remain. This is the answer. The equation is P(t)=120(1/2)^t/1620.
