Question

The mass of a radioactive substance follows a continuous exponential decay model, with a decay rate parameter of 8% per day. A sample of this radioactive substance was taken six days ago. If the sample has a mass of 2kg
today, find the initial mass of the sample. Round your answer to two decimal places.


Note: This is a continuous exponential decay model.
