Answer:

  • 523 grams
  • 52 grams

Explanation:

To find the initial amount, put 0 where t is in the formula and do the arithmetic.

A(0) = 523(1/2)^0 = 523(1) = 523

The initial amount is 523 grams.

__

To find the amount remaining after 100 years, put 100 where t is in the formula and do the arithmetic.

A(100) = 523(1/2)^(100/30) ≈ 523(0.0992123) ≈ 52

About 52 grams will remain after 100 years.
