Transcribed Image Text:A tumor is injected with 0.82 grams of Iodine-125. After 1 day, the amount of Iodine-125 has decreased
by 1.15%.
Write an exponential decay model with A (t) representing the amount of Iodine-125 remaining in the
tumor after t days. Enclose arguments of the function in parentheses and include a multiplication sign
between terms. For example, c* ln (t).
Then use the formula for A (t) to find the amount of Iodine-125 that would remain in the tumor after
8.5 days. Round your answer to the nearest thousandth (3 decimal places) of a gram.
