A tumor is injected with 0.92 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.

Which value of y will make the inequality y< -1 false?
