Answer
Explanation:
Step1: Find initial amount
When $t = 0$, $A(0)=647\left(\frac{1}{2}\right)^0 = 647$ grams.
Step2: Find amount after 100 years
Substitute $t = 100$ into $A(t)$: $A(100)=647\left(\frac{1}{2}\right)^{\frac{100}{30}}\approx 81$ grams.
Answer:
Initial amount: 647 grams Amount after 100 years: 81 grams
