Exponential and Logarithmic Models · Exercise 36

Use this scenario: A tumor is injected with $0.5$ grams of Iodine-125, which has a decay rate of $1.15$ per day.

Write an exponential model representing the amount of Iodine-125 remaining in the tumor after $t$ days. Then use the formula to find the amount of Iodine-125 that would remain in the tumor after 60 days. Round to the nearest tenth of a gram.
